The Performance Rear Diffuser for the BMW M3 and M4 is a stunning one piece carbon fibre rear diffuser.

We designed this replacement unit around OEM parts to guarantee the best possible fitment for an aftermarket item.


What's in the box

  • 1 x Carbon Fibre (2x2 Weave, CFRP) Performance Rear Diffuser

Compatible models

  • BMW M3 (2014-2018, F80)
  • BMW M4 (2014-2019, F82 F83)

Installation

The OEM diffuser is secured by 2 screws and multiple clips on the upper partition. There are two screws in the center of the diffuser that must be removed, but are not important to the factory diffuser install. Using the 8mm socket remove all 4 screws
With the screws removed simply pull the diffuser from the bumper. The top clips do not require much pressure so no body tools are required.
With the diffuser removed it is now time for install of the carbon fibre diffuser. This piece utilises all 4 8mm screws and the existing body clips. Step 1 of the installation is to lineup the clips and carefully press into place.
Now that the diffuser is loosely secured by the mounting tabs simply tighten the four 8mm screws.
