About the M3 / M4 VSX carbon fiber rear diffuser:
The PhaseCarbon M3 / M4 VSX carbon fiber rear diffuser fits beautifully onto the F80 generation M3 super sedan.
It also fits the F82 generation M4 super coupes 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 functional, sturdy yet light weight carbon fiber rear diffuser, look no further.
