Aftermarket Side Skirts

About

The best aftermarket side skirts for the Subaru WRX and STI are the ones cut for your exact generation: carbon fiber CS, OE-STI, and VR2 styles for the 2015-2021 cars, OEM-style and CS carbon for the 2008-2014 cars, and CW-style carbon for the 2004-2005 GD chassis. Side skirts tie the front lip and rear diffuser together visually, and on wider aero setups they help manage airflow along the car's flanks. Side skirts lower the car's perceived stance and connect the front and rear aero into one line, while extensions and splitters smooth airflow past the rocker panels and can reduce lift at speed. Materials split into genuine carbon fiber (twill, honeycomb, or plain weaves) and gloss black pieces that are tougher against daily scrapes. Styles here include CS, OE STI, VR2, VS, DM, and DT S207 designs, plus functional side splitters for track builds. Fitment is generation-specific: 2015-2021, 2008-2014, and 2004-2005 skirts are not interchangeable, so check your year and model before ordering. JDMuscle supplies the Tanso carbon fiber range: CS, OE STI, VR2, and VS styles for the 2015-2021 WRX/STI, Spec CS carbon for the 2008-2014 cars, and carbon side skirts for the 2020+ Toyota Supra. The house brand's strength here is variety: multiple styles per generation so owners can match the skirt to their front lip and diffuser. Seibon is one of the best-known names in carbon fiber body panels. Its skirts cover the full WRX/STI timeline, from CW-style carbon for the 2004-2005 cars and CS carbon for the 2008-2014 cars to OE-style carbon for the 2015-2021 generation. OLM targets the value end of Subaru styling, with DT S207, DM, and CS style side skirts for the 2015-2021 cars in gloss black and carbon fiber finishes. OLM parts are popular with owners who want the look of special editions like the S207 without the special-edition price.
