when i go to tracks that are relatively close to where i live, i often install my r-comps at home and drive to the track on them. however the ride is very harsh. the tires pull the steering wheel left and right as i travel over cracks and crevices. and the tires kick up a LOT of debris. so i have try not to drive on them so much because i know i am making all sorts of chips on the body panels near the wheel wells.
