Enhance the rear end of your F90 M5 with the Performance V1 dry carbon fiber diffuser. Styled directly after the real M-Performance trunk lip, this spoiler features the same 2x2 weave that is found on the OEM part. All of our carbon fiber products are equipped with a pre-applied clear coat to protect against UV rays and small rock chips. Installation is simple. This is a direct replacement for your OEM diffuser. Please note that professional installation is highly recommended. 

Dry carbon fiber is superior to wet carbon fiber for several reasons. Firstly, it is much lighter due to the absence of resin, making it ideal for weight-sensitive applications. Secondly, it offers greater design flexibility, allowing for intricate shapes and custom thicknesses. Additionally, the production process is faster and more cost-effective since there is no need for resin curing. Dry carbon fiber is also more durable and less prone to delamination.

Please note that this is not an OEM BMW part. Typically ships in 6-8 business days.
