i have a stk pro4 and i ust got a tweak, but its no biggy, but has your car been on a four corner scale were the hole car is weight and shows you the weight on each wheel, my car had the same problem till i did that
just find a person at your track with four digital scales(make sure there good ones and not cheapies) and tweak out your car, my front right seemed to the be lightest on rubber tires so i add two of the 10oz. (dont quote me on that) sticky weights
hope that helps
