The new f type skirts provide the much needed protection to the side of your car. The oem design may be attractive but lacks the width to prevent debris from hitting and damaging the rocker panels. They are made out of our super resilent proprietary 3/4" TM base material. This design mounts to the underside of the oem skirt with provided hardware and adds a small wing near the back for some aesthetic effects. They are offered in black mill unfinished plastic that can be left as is or painted locally. Easy to mount, hardware included, FREE Shipping in USA
