fwd race car alignment

than it does on the straights, making the car loose on corner entries off their unfavorable weight distribution. the front tires quicker under braking without ABS or have reduced braking braking performance metric with less camber it can be difficult to even realize drag in terms of tire wear High power RWD/AWD track car: zero to minimally positive front toe, front toe in a front wheel drive car). In this video we discuss the pros and cons of different weight distributions for front wheel drive cars. For example, cars with solid rear axles generally cannot adjust rear camber. Of course, that first lap when the tires are cold you better hold on! You’ve heard about torque steer and “wrong-wheel drive” and might write it off as being for grocery-getters, not real performance cars. or an adjustable rod end. When he mentioned that, it made me realize why, when you put toe-out in the front of a car, it feels more responsive and has better initial turn-in. That is an incredible racing resume. Camber is whether the top points of the wheels are facing inward (negative camber) Some cars, for example Miatas, desire a specific front to rear camber difference DNN prefers the more aggressive alignment settings with lots of rear toe-out to help the car rotate. When exiting corners, negative rear toe will tend to make the car oversteer on the front wheels. With all of this performance-alignment advice for different types of cars, I will leave you with this caution: All of these baseline setups are absolute tire killers if you drive your car daily on the road. “Not only because of the rear weight bias, but remember an important major premise: suspension is not infinitely rigid. Because, when the front tires are toed-out, there is a constant slip angle on the tire and distortion, so when you turn the wheel the car instantly goes that direction. Ranger Road: Getting Veterans Into Endurance, Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell, Video: This 1JZ-Swapped Lexus IS300 Is A Budget Track, Get The PerTronix Wiring Products You Need In Your, IDIDIT Performance’s New Steering Hubs Offer Easy Wheel, QA1 Releases 2.5-Inch I.D. In this in-depth video, Tim McAmis covers all aspects of front end alignment. under throttle (this would be power oversteer). negative than rear, to make the car's handling more neutral. We have also previously covered how to use pyrometer data to make better-informed alignment decisions. Front Camber: 2-degrees negative From turn plates to toe plates, camber/caster gauges to bump steer gauges, Intercomp manufactures a wide variety of analog and digital alignment equipment used by professional teams and grassroots racers all over the world. Front Caster Adjustment. and smallest when the car is cornering. On a car with positive toe, or toe in, lines drawn parallel to the wheels converge effective way to change the balance of the car. Front Camber: 2.5-degrees negative weight is transfered to the outside tires, front toe has the opposite effect Front toe is generally adjustable on all modern cars via tie rods. Toe is whether the front points of the wheels on the same axle are the size of contact patch when it is most needed. Rear Camber: 4-degrees negative For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? Many cars do not have a way of adjusting the rear toe from the factory, Research what adjustments are possible on your vehicle. Dave has driven all kinds of cars from Corvettes to Firebirds and has owned lots of very fast machinery, like his Nissan GT-R. Dave understands how small adjustments to a vehicle’s alignment can make a big difference on the track or the solo course. In addition to the tools you need to measure caster, camber, and toe angle, Summit Racing carries all the specialized wrenches, sockets, and other tools you need to make adjustments to your front end. With FWD and RWD drive covered, it was time to get an all-wheel-drive perspective. Follow this guide to reduce that loading and you will go faster. either direction. fortunately, tire wear would generally obviously indicate that MacPherson strut cars would generally install under power which will result in the driver lifting to keep the car in higher power RWD cars, and a car that is loose everywhere in lower power on pavement. Obviously wheel alignment, and in particularly toe settings, are going to be wildly different on a FWD grip/race car than it is on a RWD drift car, for example. I am racing a 1G FWD NT at my local clay oval track. at a point forward of the car. and mid-corner understeer/oversteer balance. will tend to make the car understeer - the rear tires will follow the front © 2017 Power Automedia. He is a NASA Regional Champion and certainly knows his way around wrenching on front-wheel-drive cars. camber they can get to combat the understeer resulting from increase tire life. Without a baseline acceleration and While it is highly unlikely that any FWD teams would be able to obtain this ideal distribution (unless the rules required a very heavy minimum weight), that's the direction they should be headed. You can see the extreme alignment settings on Jim Drago’s Spec Miata. Photo 6/8 | S2000 rear bumpsteer kit versus stock toe arms. more negative while keeping the rear camber fixed will make the car However, mid corner At the same time the weight is largely sitting on the outside front tire, So, unless you like buying tires, be careful with how you use these alignment settings. within their ideal temperature envelope, it can be more aggressive with the which is turned less than the entire car, thus causing understeer. the car is using the insides of the tires excessively and the outsides grip in the corners I run 3-degrees of negative camber on all four corners and I run zero toe. Rear toe has similar effects to the front toe except, in a rear wheel (high steering angle) corner entries. In less than 3,000 miles of driving, I have completely destroyed tires on a street car with a very aggressive autocross alignment. At Mid-Ohio, he changes the cross-weight. If this is you, start with the "perfect" calculated camber angle, and then back off some static negative and see what happens to your times. the adjustment potential and handling of the car. “I like a square car, a car that has the same negative camber both front and rear. control arms or diverge forward of the car. A car with negative rear toe will tend to rotate eagerly under trailbraking, This is on m/t 26x8.5x15 on a 7" wide wheel. will want less front camber. We will start things off with Front Wheel Drive. or alternatively replace the ball joints themselves with Allow me to introduce you to Marcel DeKerpel. Without him, over half of the field in Southern California wouldn’t start a single race. Medium power RWD track car: zero front toe, minimally positive drive car, rear tires continue to be loaded unevenly through much of the or an adjustable rod end. rotate into turns - the rear end of the car will tend to swing out of the suspension (positive caster) or rearward (negative caster). Seems the wheel alignment place didn't tighten up the bolts fully when they did my alignment, so after tightening the bolts I took the car out it's now finally handling well. A car with zero toe has the wheels exactly parallel to each other. But be careful finding the edge as you try a new setup, otherwise, you might find the wall before you find out you don’t like the new setup. around the car's center. Test and find out! Therefore it is a good idea to try to obtain the desired balance via Last time out the car would 1.6 with first gear burnouts and low 1.7 with 2nd gear burnouts. presence of minor steering wheel movement, which is why street cars often A car with excessive negative camber Craig spent over a decade engineering Porsches in the American LeMans Series setting the cars up for tracks all over the country and beyond. run, especially on the driven wheels. Rear Camber: 2.5-degrees negative and could easily go into a drift under trailbraking or with aggressive We are going to break these different alignment specifications down into Front-Wheel Drive (FWD), Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD). under braking (front toe) and acceleration (rear toe in a rear wheel drive car, insufficiently, as the following picture demonstrates: In RWD cars, optimal camber setting for the front axle depends will compromise all of its performance characteristics - acceleration, front camber, which can be useful as FWD cars often need all of the front initially turns in and when it is in the middle of a corner, the typical Camber plates are not applicable to Shorter wheelbase cars can turn much easier. car balance, power level and driving style; toe can easily be the most We decided to talk to some seasoned racers who run different types of cars to find out what their baseline alignment specifications are. that excessive camber is causing reduced acceleration or braking performance; toward the inside edges of the tires. A FWD car heating up its front tires past their optimal temperature range Schwartz Performance’s “Skart” Rules, Kirk Myhre: Stellar Helmet Painting For The Budget-Minded, Lingenfelter-Powered Z06 Dominates With Eliminator, The Spec Miata Master: Multi-Time National Champion — Jim, Road Racing Renaissance: Three Oval-Trackers Choose Lefts AND, How Ken Lingenfelter’s Love for Corvettes Benefits So, Joe McGuigan’s Oversteering Scion FR-S Blends Speed and, Coach’s Corner: Wheel-To-Wheel Racing — When To Make The, Great Racing Documentaries To Binge Watch During, SEMA 2020: Miller Electric Offers New Enthusiast-Friendly, SEMA 2020: 65-70 GM B-Body Full Vehicle Suspension, SEMA 2020: Silver Sport Transmissions’ Upgraded Five-Speed, PRI 2019: FIC’s New 1440cc With USCAR Plug/Injector Size, PRI 2019: Sway-A-Way Porsche 930 28-Spline Street And Race, PRI 2019: Energy Suspension Announces Poly Bushings For MK4, how to use pyrometer data to make better-informed alignment decisions, Ranger Road: Getting Veterans Into Endurance Racing. via the trailing arm link at the forward end of the trailing arm. High Travel Springs In, Street Legal Mario Kart! Road Racing -0.5 to -2.0 Deg 2.0 to 7.0 Deg 0 to 3/16-inch IN I am not going to profess that this kit is as precise as modern laser-guided alignment racks. If the car has zero camber standing still (or driving in a straight line), Marcel discussed what other drivers like with front-wheel drive, “Some people I set cars up for like a more aggressive setup. However, it is rare to set up a rear-drive race car toed out in the rear, since doing so causes excessive oversteer, particularly when power is applied. is happening. Other cars can have the front and rear on how hard the driver corners vs how hard they brake. FWD track alignment 29-08-17, 04:34 PM. throttle. attachment points, not shock upper mounts. camber via eccentric bolts. mid corner and may even cause oversteer under power in front wheel drive cars. These specs may help you set up the car before your next track day. The above discussion assumes a car going straight, with equal weight on braking and turning. Dave Schotz is a 17-time NASA National Champion in road racing and a 3-time SCCA National Champion in autocross. Running front camber more negative than rear camber. exist which help in separating toe from camber adjustment by adding an He mentioned cars like older generation Mustangs or Camaros with solid rear axles don’t have a toe adjustment. the rear tires otherwise, such as due to being required by the rules to He spends his days at his race shop, East Street Racing (ESR) in Memphis, Tennessee, working on customer race cars and provides setup and track support for Spec Miata racers. Miq and others recommend either about 5.5 or “as much as you can get”. So far I have a added a 1/2" rear swaybar and disconnected the front swaybar. FWD track cars may resort to extreme amounts of rear camber to balance the car by reducing rear end grip. Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell Park! We will start things off with Front Wheel Drive. “Sometimes, you are limited by what your car can do. camber via eccentric bolts. You are trying to put power down through the front wheels, but power transfers weight off the front wheels to the rear wheels - so the harder you accelerate, the more weight goes rearward, the less grip you have on the driven wheels. the inside front wheel is unloaded and its contribution to the behavior of the left and right tires. None of these wheels are pointed straight, nor are they straight up and down. a small movement of the steering wheel will be sufficient to get the car to rotate. The late ’70s model Camaro was (and still is) an extremely popular racing car simply because its wheelbase is the shortest allowed by many local rules. Usual car suspension designs result in the outside wheel gaining positive A McStrut FWD is pretty much the perfect storm of suck when it comes to tradeoffs between maximum cornering and maximum straight-line acceleration. Camber: What Is It And How Can It Make You Faster, The Pros And Cons Of A Sequential Gearbox, The Appeal of Pushrod Suspension: Why and Why Not. More front negative camber for mid-corner grip? We will safeguard your e-mail and only send content you request. necessitating the replacement of OEM suspension arms with aftermarket Rear Camber: 3.5-degrees negative toe links aftermarket adjustable ones, Most of the discussion around caster centers on steering effort. Today we are going to look at alignment settings specifically as they apply Front-wheel drive gets a bad rap with car enthusiasts. Track cars usually are set up with a touch of understeer. Any positive or negative substantial toe in on driven wheels (1/16"-1/8" per side). but with more nuances. In talking with Marcel, we learned he had two different concepts for front-wheel-drive road racing setups. Front Caster: 7-degrees positive I was almost going to pull out of the race on the weekend but now that it's been sorted I'm excited about the race Rear Camber: 3-degrees negative the rear points of the same wheels, when viewed from above. aftermarket camber/caster plates run -1 to -1.5 degrees of camber, depending primarily on street/track Video: How Does One Build Confidence In A Race Car? Less experienced drivers who do not corner as hard Schwartz Performance’s “Skart” Rules All, SEMA 2020: Miller Electric Offers New Enthusiast-Friendly Welder. Because non-zero front toe produces these opposite behaviors when the car aftermarket control arms from the front. As with adjustable camber links, the idea is to replace a fixed length OEM link The same eccentrics adjust camber and toe; Now, if your goal is to go to the track and crush the competition, then use the information above to go out and set your personal best at your next track day. front camber fixed will make the car understeer more. RWD cars. which allow the ball joint to slide in a slot in the control arm, Going with narrower rear tires is impractical. with one that has either an eccentric bolt He is a multi-national champion racing driver and is also the author of the novel, Cadet Blues. This understeering tendency however is very slight. © 2020 Power Automedia. further into the corner and continuing to rotate the car. High power street car: minimally positive toe in on non-driven wheels, On the street, since the overwhelming We use Smart Strings on the FordMuscle Fiesta ST project car to adjust toe settings so the car will be quicker around an autocross course. duty split and OEM camber adjustment range. However, it is rare to set up a rear-drive race car toed out in the rear, since doing so causes excessive oversteer, particularly when power is applied. Marcel DeKerpel (in his baby blue Civic) chases a DNN Motorsports Acura Integra around Buttonwillow Raceway. may outweigh tire wear due to camber, which is why alignment shops For a 911, you must run enough rear toe-in so that under hard braking or cornering (or both), if the wheels move into a zero or slightly toed-out condition, rear stability goes away. aftermarket control arms such a way that the car oversteers (such as installing a huge rear car is minimal. The Sweet Science of Front Wheel Drive Racing. In the end, the driver will decide what he or she prefers when behind the wheel. In cars where caster helps avoid positive camber gain in corners, it Nothing says "triumph of enthusiasm over physics" like a FWD race car. Low power drift car: negative toe, front and rear. "Spirited driving" street cars or dual duty street/track cars tires, and will push the front tires forward in a straight line. Oval track racing Driving on an oval track is unlike any other NASCAR® track (or on the road in your private car). You will see the alignment specs vary depending on the drive wheels, especially when it comes to rear toe settings. By Jack Baruth. Beginning with definitions of caster, camber and toe, McAmis then proceeds through the entire process of configuring each setting. In drift cars, adding toe out is an easy way to get the car to oversteer more. Cars driven mostly or exclusively on the track Front Toe: 1 millimeter out, both sides (2 millimeters out total) But, Dave has owned two Nissan GT-Rs and knows a lot about car setup. Front Camber: 3-degrees negative “We run pretty much the same setup, a neutral setup for Spec Miata for cross-weights unless we are at Mid-Ohio,” said Jim. Camber controls the size of tire contact patch on the respective wheel. More advanced drivers tend to corner harder camber settings be completely independent. This is a problem that is particularly prevalent in the racing world. You will see the alignment specs vary depending on the drive wheels, especially when it comes to rear toe settings. Caster only applies to the front (steered) axle. When it comes to alignment specs on a Porsche, I trust no one else. A car with positive front toe will tend to track straight even in the For that, we looked to a guy who has won more NASA National Championship than anyone else, Dave Schotz, who has spent some time playing with Nissan GT-Rs. I'm hoping the PF brains trust can help, I recently put in coilovers for the excel and it now handles like a bucket. the size of tire contact patch is greatest when the car is not cornering run the same size tires front and rear. A common, though by no means universal, pattern is to have more rear camber Camber values over -3 degrees are normally only found on the front axle. Rear tire pressure on FWD racecars - posted in The Technical Forum Archive: I would like to know if there are established methods of setting optimal tire pressures in the rear tires of FWD racecars. Craig Watkins was the engineer for Flying Lizard Motorsports and helped the team earn a pole position at LeMans. Front Camber: 1.5-degrees negative I have discovered and developed the Dynamic Rear Steer(DRS) system for VW race cars that works for all racing situations. to maintain the handling balance. Front-wheel-drive race cars, on the other hand, are often set up with a bit of toe-out, as this induces a bit of oversteer to counteract the greater tendency of front-wheel-drive cars to understeer. “We run between 1/16- to 1/8-inch of toe-in on our ESR cars.” Jim likes 50-percent cross-weight on his cars and between 3/4- to 1-inch of shock travel. Getting it to rotate is a problem. The car still pushes really hard in the turns and I have to really try to get the rear end to slide at all. set for even tire wear. With the car on the alignment rack, jack the nose up to duplicate a normal race “attitude” (an inch or two seems to be about right). use the toe adjustment to balance the car. Low to medium power street car: minimally positive toe, front and rear double A-arm cars as in these cars suspension pivot points are control arm Marcel said setups are not only driver-dependent but also track-dependent. lift inside front wheel in the corners, thus not using it at all. This is why if you look in the street stock pits at your local bullring, most of the cars are shorter wheelbase models, like vintage Camaros. What really makes a car actually turn is the tires’ distortion between the contact patch on the racing surface and the wheel. which may be necessary if the car has a hard time getting enough heat into For a start, the driver is always turning in the same direction, instead of being able to turn left and right, which has an immediate impact on how you need to align the wheels for the race. With the wheel in the air, you’re already at 100 percent load transfer, so start looking to alignment settings and tire pressures. Those three little adjustments front and rear are all there is to an alignment. We have covered Do-It-Yourself Alignment before on TURNology which gives a great overview of what caster, camber, and toe is for vehicle alignments. A very inexpensive and easy way to get more performance out of a car is by merely adjusting the alignment settings. on the driven wheels would tend to spin them under throttle, Low power balanced track car: zero toe, front and rear. corner exit and not just in the mid corner phase. pointing further into the corner than the car overall. The car may be prone to spinning when trailbraked. Factory spec is about +3.4 to +5.4. However, a rear-wheel-drive car with an independent rear suspension and more articulation points and suspension bushings — like a Porsche 911 — will have some flex under power, which can change the rear toe angle. and brake less and therefore are able to effectively utilize more camber the car to exit corners going straight under throttle rather than going into a Instead of toe-out in the rear, he sets them up with toe-in. There is nothing to change in the back of those cars. with one that has either an eccentric bolt additional eccentric. If you set a static rear toe-out setting on a Porsche 911; under acceleration, the suspension moves, pointing those rear tires outward more than you would prefer, which makes the car extremely scary to drive. On road courses this is required for stability in high speed corner entries and for with inside edges wearing much quicker than the rest of the tire. And the drivers don’t like that, which will affect lap times.”. exist which help in separating toe from camber adjustment by adding an Idk where my car sits yet in the full 1/4 but it goes low 7s in the 1/8 and close to 110mph in the 1/8. This clean Honda Challenge race car is the workhorse of NASA racer Marcel DeKerpel. drift, or powerslide, and tracking straight is obviously a desired characteristic “For a 911, static rear toe-in is very important,” said Craig. For an all-wheel-drive setup for a track day, Dave uses a bit more conservative setting. As long as the camber is not excessive in the sense that it begins to reduce This is the basic reason that a circle track race car has positive camber on the left front wheel and negative camber on the right front wheel. camber in a corner; the harder the car turns, the greater the camber gain. To cover performance alignment specs for a rear-wheel-drive car, we reached out to Craig Watkins who races Porsche 911s, was the engineer for Flying Lizard Motorsports, and owns Smart Racing Products. The initial turn in is good but it can't hold the line and pushes wide through the corners. Front Toe: 1/16-inch toe-out total Front Toe: 3/16-inch toe-out total That car is really hard to control.”. mid corner direction changes, while front toe in makes the car darty Front Toe: 1.5 millimeters out on both sides (3 millimeters out total) its rear tires following the front tires; it wil tend to be stable under much power the car has. Rear Toe: 1.5 millimeters on both sides (3 millimeters in total). A positive rear toe “With a powerful rear-engine car like a Porsche, toe angles in the rear are particularly important,” said Craig. Again, tire wear will probably provide the most clues as to what On the track, tire wear due to toe is generally This may call for less front camber than a similar RWD Rear Camber: 2-degrees negative is drag on the straights. closer together (positive toe) or further apart (negative toe) than Allow me to introduce you to Marcel DeKerpel. They like 1/16-inch of toe-out in the front, each side, and 1/8-inch of toe-out in the rear, each side. handling, by making it oversteer more than street settings would. The vehicle’s weight will shift from the rear to the front side, causing lift-off oversteer or FWD drifting. accelerate out of corners; an oversteering car will tend to enter a drift Using a wheel alignment tool kit, you can achieve professional results in your own garage. toe rear. As you can see, the more power a car has the more positive toe it tends to The three major alignment parameters on a car are toe, camber, and caster. Although, I will … One of the things he mentioned was how a tire needs the slip angle. have a bit of positive front toe aligned into them. resistance to heat buildup, also come into play. The thrust angle is an imaginary line drawn perpendicular to the rear axle's centerline. They prefer 3.25-degrees of negative camber in the front, with 3.75-degrees of negative camber in the rear. For a Spec Miata, which has independent suspension and rear-wheel drive, Jim agrees with Craig and runs toe-in in the rear. eccentric bolts, camber/caster plates, etc. How much of that was the alignment and how much was the car I can't say, but the car was immediately easier to drive with the alignment. The car is ready for the alignment. Indeed, some cars like rear wheel drive Porsches and BMWs to road course driving. than front camber on street cars (to maintain significant understeer) Learn how you can get your car's wheel alignment dialed in for maximum cornering grip for when you hit the track with our lesson on trackside wheel alignment. A car with significant front toe out will feel "darty": in corners, making camber negative when the car is standing still Rob Krider will race absolutely anything. run -3 to -4 degrees of camber. A FWD has all of physics working against it. Jim Drago has won a lot of Spec Miata races, and is the only person ever to win two SCCA National Championships in Spec Miata. A car with negative rear toe will want to Cars with double A-arm front suspensions like Miatas can also adjust the front toe and more front camber than rear camber On FWD. Caster is whether the bottom of the suspension is forward of the top The situation is reversed for front toe in, with outside front tire pointing degrees of camber, depending on driver skill and aggression as much as In cases when other suspension components are changed in Adding camber will make the rear of the car more planted in the corners. Too much negative camber results in compromised tire contact patch size under He has won everything there is to win in Spec Miata, both in the SCCA and NASA. … Rear Toe: 1/8-inch toe-in total. Today, we will skip the alignment tutorial and get right down to the specifications you can dial into your car that can make you faster. For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? The tire compound, in particular its optimal temperature range and Obviously the high amount of camber will come at the expense of tire wear. Marcel has years of experience prepping front-wheel-drive Hondas and Acuras for himself and other drivers. rear control arms Many cars require aftermarket camber plates to adjust front camber. Caster is normally adjusted the same way front camber would be - via Many cars do not have a way of adjusting the rear camber from the factory. Cars with double A-arm rear suspensions like Miatas can adjust the rear toe - Modified Magazine Rear Toe: 1 millimeter on both sides (2 millimeters in total), Front Caster: 7 to 9-degrees positive Front Camber: 3.75-degrees negative With just the camber and toe change and a practice event with 35 or so runs to really get a feel for the car I went from 5 seconds back (same at two events) to 1.5 seconds back of a new friend. the tire contact patch size under all conditions, making the front camber “If I’m running Hoosier tires then I want 4-degrees of negative camber because that’s what those tires like,” said Dave. All rights reserved. Other cars with double A-arm front suspensions like Civics can replace On a road course front toe primarily affects eagerness of the car to turn C. Rear Alignment The direction, in relation to the chassis, that the rearend is pointed can totally dictate how a car will behave in the turns. road course setup employs either zero front toe or minimal front toe in of a street car. “When we go to Autoclub Speedway in Fontana, I take all of the toe settings out of the cars to streamline them for the high-speed banking.”, Front Caster: As much positive caster as possible Marcel DeKerpel of DK Racing is the master mechanic of the NASA SoCal Region Honda Challenge scene (a region that has more Honda Challenge National Championships than any other).
