RACING SPORT CONCEPTS - Carbon rear diffuser BMW M3 F80 & M4 F82

Reinforce the diffuser fins
The 3-piece Racing Sport Concepts BMW rear diffuser sets your M3 or M4 apart from all other diffusers available on the market. The two side panels are made from double bonded carbon to reinforce the diffuser fins and give a nice clear coated finish.

The center section features two more double-glued fins that are removable at the bottom and have a central vent to allow the hot air from the exhaust to escape. This functional aerodynamic piece not only directs turbulence away from the rear tires but also creates a central vacuum area to reduce lift at the rear of the vehicle.
