The rocker below the IS's doors is the longest flat surface on the car and the one the factory left plainest. These skirts fill it — in primed FRP, for less than the carbon set.
Same Feral Auto design, same mold, same lines as the carbon version. Built from FRP and shipped primed, ready for your painter to match your factory color code. Sold as a matched pair, driver and passenger side.
Pairs with the FRP Roof Spoiler and FRP Rear Diffuser across the same year range, and the 2026+ FRP Front Spoiler. All four come together in the FRP Aero Bundle Kit for the 2026-2027 IS350 F-Sport and F-Sport Design.
Fits the 2021-2025 Lexus IS300 and IS350 (Base and F-Sport), the 2022-2025 IS500, and the 2026-2027 IS350 F-Sport and F-Sport Design.
Why FRP
FRP is what most painted aero has been made from for decades, and it is the right answer when you want the shape in your car's own color rather than a carbon weave. It is strong, light, takes primer and paint evenly, and it is straightforward for a body shop to repair if it meets a curb — which is not true of carbon.
Side skirts are the panel most likely to take that curb hit. On a long rocker run, being repairable is worth more than it sounds.
Finish
Ships primed in gray, ready for paint. Photos show the parts painted gloss black. For a carbon weave finish, see the carbon fiber version, available in gloss, matte, Honey Comb and forged.
