This is our new CF side diffusers by Klass Carbon for the F80/F82 M3 and M4. Designed to mount directly onto the stock body. The carbon fiber diffusers are designed for the ultimate look on your BMW with features such as light-weight, high-durability and precise-fitment. Klass Carbon aero products are both highly visible and saves weight at the same time. Be sure to check out our full line of F80/F82 M-car products on the site here and feel free to ask any questions!
This side diffuser comes in a glossy carbon fiber finish. Every product we sell is rigorously tested on our own shop demo cars to ensure fitment is 100% spot on. We don't sell any products unless we would use it on our own cars!
Installation should take no longer than 1 hour.
