You were correct, from what I understand he rubs on the plastic covers that protect his belts on pass side and the transmission cover on the driv.side. He says this happens when he turns at 30 miles/H. You have GR-2s with Teins springs not super rally car suspension , no offense. Thats your problem right there, soft suspension + turns at high speed=car weight shifts to that side, pushes the tire inward and there you have it. Slow down and problem solved.
