About the M3 / M4 Performance Inspired carbon fiber rear diffuser:

This exquisite Kies Carbon M3 / M4 performance inspired carbon fiber rear diffuser is a beautiful work of art that fits perfectly onto the F80 generation M3 super sedan.

It also fits the F82 generation M4 super coupes, and the F83 generation convertible as well!

This rear diffuser not only looks amazing, it's also aerodynamically designed to efficiently channel air and reduce drag. So not only does this upgrade look good, it is also functional.

For anyone looking to upgrade their stock M3 or M4 with an aggressive yet practical, sturdy yet light weight carbon fiber rear diffuser, look no further!

Professional installation is highly recommended.
