Update your G80 M3 or G82 M4 with the Performance V1 rear diffuser, designed to refine the factory rear profile without looking overdone. It's an OEM+ upgrade that sharpens the stock styling rather than fighting it.
The Performance V1 is constructed from genuine 2x2 prepreg carbon fiber for a lightweight, rigid panel with a clean, high-quality finish. It's a direct replacement for the factory G8X M3 and M4 diffuser and installs using all OEM mounting locations, with pre-drilled holes that reuse the factory hardware for a straightforward install.
Pair it with our Performance V1 carbon fiber rear extensions for a more complete rear end setup. Have questions about fitment or installation? Reach out through our contact page.
Professional installation is recommended. This is an aftermarket product and is not affiliated with or produced by BMW.
