BMW F80 M3/ F82/83 M4 1x1 Carbon Fiber rear diffuser (Finned Style)
We love the look of the OEM M-Performance Rear Diffuser BMW created for the F80 M3/ F82/83 M4, but like with most of the parts it was not aggressive enough and got lost in the aggressive rear bumper lines. We took styling cues from the OEM BMW piece and added our own aggressive styling to it while still maintaining a OEM look. Our Version is made from 100% Pre-Preg Carbon Fiber and sits 1.5" lower than the factory diffuser to help cover the large factory Muffler (or any aftermarket version) We have also extended the top portion to stick out from the bumper to give an aggressive side view. Optional Bumper extensions are in the works to transform this mild looking piece into a full length looking race diffuser. Direct fit, no modification required. Remove your factory piece and re-install our new lightweight CF piece.
