Carbon fiber rear bumper extensions help give the rear end of your F8X M3/M4 a more aggressive, aftermarket look. These extensions are made of 100% genuine carbon fiber and help compliment the already aggressive body lines of the F8X generation. Both pieces feature a 2x2 weave, which is the same weave found on OEM F8X carbon fiber. 



Please note that these are not the same extensions that are included with the V Style diffuser. These are intended for standalone use. Drilling is required, we recommend using 8-10 3/4in self tapping screws with washers. Double sided adhesive is not required for installation.

This is not an OEM BMW part.
