for those who run setups that allow crazy steering angle with the wheel locked all the way to one side, its so tires dont rub. with crazy setups, you could get a 225 tire to rub up front at full lock. is it worth it? maybe if you're going to have a track car to drift only and are going to have 1 million degrees of steering angle. to me, not worth it. looks clean with real paint job and stuff though.
