You have probably thought of this, but please bear with me. Check the clearance between the top outside edge of the rear tires and the inside of the fender lip. I know from experience that sometimes a really sharp turn at speed can cause enough lean to let the tire rub the inside of the fender. This can happen especially if the rear coilovers are adjusted so the rear ride-height is pretty low. Just a thought....good luck. Bob
