Description
xThe Kies Carbon M3 / M4 Varis style carbon fiber rear diffuser undertray fits beautifully onto the F80 generation M3 super sedan. It also fits the F82 generation M4 super coupes, and F83 generation convertibles as well.
This will install along side the M Performance carbon fiber upper diffuser as well. If you didn't get the carbon package on your M3 / M4 you can pick up on of our Kies Carbon F80 / F82 rear diffusers to add to the collection.
This rear undertray is one of the most complex, and stunning pieces of carbon we have ever seen. 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.
