Protect your expensive paint job with this Wheel Well Liner Kit for the rear of your GTM. These liners protect the fiberglass body above the rear tires from rock strikes that will produce cracks in the body and ruin your paint. Installation is very simple by forcing the liner up into the wheel well so that the liner is wedged between the inner aluminum panels and the body of the car. The liners include a high quality rubber bulb seal to keep the liners locked in place against the body. Liners attach to the aluminum panels as shown in the photos below.
