2.5 Rear Diffuser Kit (Upgrade/Conversion)


In stock


We’ve taken our carbon fiber 2.5 Roadster rear diffuser to the next level. Now for the first time ever, you can complete the package with our carbon fiber winglets and undertray. Stainless steel mounting hardware included.

This kit will fit all original Roadsters. It replaces all the lower rear plastic pieces on 2.5 Roadsters, and has everything needed to convert 1.5 and 2.0 Roadsters to the 2.5 design. Since its launch, our 2.5 diffuser has been highly desired and installed on several 2.5 Roadsters. Owners of 1.5s and 2.0s have asked what would be required to perform a 2.5 conversion. Here is our answer.
