One of the most important aspects of car setup is the static weight distribution and the cross-weight percentage. Why? Picture the following:
Your car is really fast in right-hand turns, but under-steers in left turns. If you get the car neutral in left turns, it over-steers in right turns. The situation is frustrating. You’ve tried springs, shocks, different bars, neutralizing the anti-roll bar, and nothing seems to work. Even on a track with mostly right-hand turns, the problem in the left-hand turns cost a lot of time.
While several different setup parameters could have caused this situation, a likely cause is excessive cross-weight.
Cross-weight percentage compares the diagonal weight totals to the car’s total weight. To calculate cross-weight percentage, add the RF weight to the LR weight and divide the sum by the total weight of the car. Cross-weight is also called wedge: If the percentage is over 50 percent, the car has wedge; if below 50 percent, the car has reverse wedge.
More wedge means that the car will likely under-steer more in a left turn. The advantage to wedge is that the left rear tire carries more load, so the car drives off the turns better. But in a right turn, the opposite occurs and the handling is worse. In almost all cases, the loss of cornering performance in one direction is greater than the gain in the other direction.
With our latest computerized corner scales we can dial your car in to handle at its optimum possible setting!
