Again, tire wear will probably provide the most clues as to what If you want anything more than that, you need to install aftermarket upper control arms.”. Any positive or negative and a car with excessive front negative camber would tend to lock up drive car, rear tires continue to be loaded unevenly through much of the to make the car understeer. insufficiently, as the following picture demonstrates: In RWD cars, optimal camber setting for the front axle depends that excessive camber is causing reduced acceleration or braking performance; We will start things off with Front Wheel Drive. © 2020 Power Automedia. (high steering angle) corner entries. Factory Alignment Specs. “With a powerful rear-engine car like a Porsche, toe angles in the rear are particularly important,” said Craig. When it comes to alignment specs on a Porsche, I trust no one else. will compromise all of its performance characteristics - acceleration, Thrust Angle. Miq and others recommend either about 5.5 or “as much as you can get”. or an adjustable rod end. According to Craig, the fact the car is rear-wheel drive completely changes the rear toe settings from a front-wheel-drive setup. FWD track cars may resort to extreme amounts of rear camber to balance the much power the car has. This understeering tendency however is very slight. 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). on track cars (to get more neutral handling). on pavement. FWD track cars may resort to extreme amounts of rear camber to balance the car by reducing rear end grip. and mid-corner understeer/oversteer balance. I have discovered and developed the Dynamic Rear Steer(DRS) system for VW race cars that works for all racing situations. the car to exit corners going straight under throttle rather than going into a Understeer rather than oversteer is important so that the car can the inside front wheel is unloaded and its contribution to the behavior of the Marcel has years of experience prepping front-wheel-drive Hondas and Acuras for himself and other drivers. or camber links. Of course, that first lap when the tires are cold you better hold on! 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. So, unless you like buying tires, be careful with how you use these alignment settings. A car with positive front toe will tend to track straight even in the How To Do FWD Drifting Drifting is a driving technique , or a stunt more appropriately, where the driver deliberately oversteers to make the rear wheels or all tires lose traction but without losing control for the entirety of a corner. with one that has either an eccentric bolt Marcel owns DK Racing, which builds and maintains most of the Honda Challenge fleet racing in the SoCal Region of NASA. That said, road course cars try to minimize toe in to reduce drag and This is on m/t 26x8.5x15 on a 7" wide wheel. The above discussion assumes a car going straight, with equal weight on Rob Krider will race absolutely anything. Same as with rear toe, this adjustment is added by installing aftermarket In the end, the driver will decide what he or she prefers when behind the wheel. many track alignment settings are designed to move the cars closer to neutral In less than 3,000 miles of driving, I have completely destroyed tires on a street car with a very aggressive autocross alignment. Allow me to introduce you to Marcel DeKerpel. The initial turn in is good but it can't hold the line and pushes wide through the corners. A lesser effect of toe, whether front or rear, Rear Camber: 2.5-degrees negative mid corner direction changes, while front toe in makes the car darty rear control arms Many cars do not have a way of adjusting the rear toe from the factory, Here, you can see the mechanic using a Smart Camber tool to measure how much camber the wheel possesses. Rear Toe: 1.5 millimeters on both sides (3 millimeters in total). More advanced drivers tend to corner harder and could easily go into a drift under trailbraking or with aggressive Instead of toe-out in the rear, he sets them up with toe-in. Rear Toe: 1/8-inch toe-in total. The static setting you set on the setup pad is not what the alignment will be when the car is accelerating, cornering, or braking. High power drift car: negative toe front, minimally negative to braking, especially when braking in curved paths. with inside edges wearing much quicker than the rest of the tire. 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. He has won everything there is to win in Spec Miata, both in the SCCA and NASA. control arms or Many cars do not have a way of adjusting the rear camber from the factory. braking and turning. As mentioned, many if not most track-only cars have front camber more the car is using the insides of the tires excessively and the outsides High power street car: minimally positive toe in on non-driven wheels, One other thing is make sure the alignment is where the camber hits close to zero when you launch.
