Try a stiffer spring on the right rear. this is what full size Drag racers do. It also works on RC. If that doesnt help then you have something broke... This type of Torque twist happens every day at the drag strip. Uni-body cars are known for this problem.This can get so bad that the car will shoot into the left lane . When I first got my TXT it would actually torque the body into the tire on the right side while riding a wheelie. But that was w/ mod. motors w/ 8 tooth pinions at 14.4 v.
