The Feed Style Side Skirts For Mazda MX-5 NA NB gives your car a real aero advantage. By preventing air from passing under the car, air pressure is reduced. As air pressure is reduced, the car generates less lift, making it more stable at high speeds. Made from polyurethane, the sideskirts are durable enough for life on the road. They can survive scrapes on speed bumps and driveways longer than fibreglass. These side skirts give your Mazda MX-5 an aggressive look, enhancing the styling of the original car.
