From here, you may adjust the wheel alignment, the chassis ride height, brake bias and wheel lock.
The Align menu's interface is similar to that of the Chassis menu. The bars and split screen at the lower right are identical, while a picture of your Viper, depicting a wheel's camber, toe-in, brake bias, or wheel lock, replaces the Chassis menu's bump/rebound screen.
Toe-in is the angle of your wheels relative to the direction of chassis travel. The toe-in is positive when the front of the wheel points toward the chassis, and negative when the front of the wheel points away from the chassis. Negative front toe-in makes the Viper stable under braking, and tend to push on turn in. Positive toe-in at the front makes the car turn in better, although a bit darty under braking. Rear toe-in always should be negative; otherwise the rear of the car will tend to drive around the front.
Camber is the vertical angle of your wheels relative to the chassis. If the top is closer to the chassis than the bottom, the wheel has negative camber; if the bottom of the wheel is closer than the top, the wheel has positive camber. Negative camber is almost always a good thing. Positive camber rarely is!
Height is the ride height of the car. In general (and this is a big generalization), lower is better. Sometimes it helps to raise the tail slightly. This increases drag and slows straight line speed, but it also gives the chassis a little more grip in the high speed bends.
Brake bias determines which set of the Viper's disc brakes, front or rear, do the most share of the stopping. Under braking, the cars weight transfers to the front, so it's a good idea to place most of the braking emphasis here. On the other hand, too much front brake bias not only causes the front wheels to lock up (stop turning), But it under utilizes the rear brakes. Conversely, too much emphasis on the rear brakes causes them to lock up before the fronts, causing the car to spin.
Wheel lock is the measure (in degrees) that the front wheels turn to either side of dead center. The greater the number, the sharper the Viper will turn. There's a downside, however. More wheel lock increases a car's steering sensitivity. In other words, cars with a lot of wheel lock are difficult to drive straight.
