This is an ideal upgrade for enthusiasts looking to maintain an OEM plus aesthetic while adding a more refined rear profile. Update your G80 M3 or G82 M4 with the Performance V1 rear diffuser, designed to enhance the factory styling without appearing overdone.
The Performance V1 diffuser is constructed from genuine 2x2 prepreg carbon fiber, offering a lightweight yet rigid design with a clean, high quality finish. It is engineered as a direct replacement for the factory G8X M3 and M4 diffuser and installs using all OEM mounting locations. Pre drilled holes allow the diffuser to reuse factory hardware for a straightforward installation.
This diffuser pairs well with our Performance V1 carbon fiber rear extensions for a more complete rear end setup. If you have any questions regarding compatibility or installation, feel free to reach out through our contact page.
Professional installation is recommended. Installation instructions are not included.
