P Style Carbon Fiber Diffuser w/ Carbon Undertray - F80 M3 | F82/F83 M4

This is the most aggressive rear diffuser we offer for the F80 M3 and F82/F83 M4; it is also our most popular product! The P-Style diffuser gives any M3 or M4 an aggressive, aftermarket look that you just can't get with other diffusers on the market. Like all of our carbon fiber products, this one has an OEM-quality clear coat to protect against the harmful affects of UV rays. All 4 pieces feature a 2x2 carbon weave. Professional installation is highly recommended for this diffuser. This diffuser uses ALL OEM mounting points, no drilling necessary.

Our diffuser features pre-drilled holes on all areas except for the fins. We recommend using OEM BMW 8MM speed clips and screws for mounting, please note that these are not included but can be purchased from most hardware stores and BMW dealerships. For any questions please feel free to send us an email or reach out via the contact form. 

These ship from our location in Los Angeles, CA. Shipping typically takes 3-6 business days.

DISCLAIMER

We recommend attaching the two large fins on undertray to the center diffuser piece using 2-4 self tappers to properly secure the undertray. We do not sell the undertray by itself. If you have questions regarding installation on this diffuser please contact us! Professional installation is highly recommended.
