Rally Armor Mud Flaps For Subaru Impreza Models are constructed from polyurethane and designed to perform consistently in all weather conditions and diverse road conditions. The flexible UV-resistant urethane mud flaps are durably abrasion-resistant and long-wearing. Providing drivers with four-corner protection, Rally Armor mud flaps are crafted for variable temperatures. They help to protect against paint-damaging salt spray, gravel, and tar grime that wears your car's finish away. Whereas vinyl and rubber manifest steady, visible material curling and wear over time, strong urethane construction maintains its form.
