The BMW M3/M4 in general is a great looking car with plenty of aggression, the rear however lacks with the flat OEM diffuser. On a lot of high performance cars you tend to see a nice Venturi effect rear diffuser, Carbonwurks brings that needed look to the M3/M4 with a bold and defined carbon fibre diffuser.
The carbon rear diffuser is made up of lightweight and strong carbon fibre and reinforced with a glass fibre composite, this is called CFRP and is the same type of carbon used on the roof of the M3/4 from factory. The diffuser once made is then finished off in a high gloss lacquer, after which the carbon is hand and machine polished then sealed in with a very high carnauba content wax from our partners Race Glaze, to give both depth and protection.
The diffuser is a direct replacement for the OEM plastic diffuser, no modifications are needed and is a quick and easy install. Professional installation is recommended however the diffuser can be changed over in under 5 minutes with only 4 bolts and clips holding it to the car.
Every single diffuser is throughly checked for fitment and is tested on our rig to make sure the diffusers fit perfectly every time.
