Fitment:

BMW M3 G80 g82 carbon fiber rear diffuser with f1 style led stop light

The carbon rear diffuser for the G80 gives the ultimate look and road presence to make this car stand out

Removal of the rear bumper is required to wire the led to the brake light and to also remove the OEM diffuser correctly, the OEM fastening clips have a lock inside the clip which needs to be pressed down from inside to safely remove without the bumper or the stock diffuser. Many people that were familiar with the F80 M3’s may try to pull the same way, we strongly advise not to do that as it would require a great amount of force, removing the bumper is actually a very easy process.

Easy to install giving the perfect finish with oem fitting
