Make the rear end of either your 2015-2021 WRX or STI better looking and more aggressive with the OLM Carbon Fiber Rear Diffuser!
This rear diffuser is a huge upgrade over the plain molded plastic that every WRX and STI has. Dry carbon fiber construction provides strength without adding bulk. Therefore the diffuser can contour your rear bumper better than similar products on the market. This is why it doesn’t dwarf our exhaust tips.
Designed in Japan and test fit right at the OLM facility
