Carbon Fiber Rear Diffuser for BMW 6 Series Gran Turismo G32 M Sport 2017-2021 (Pre-LCI)

Carbon Fiber Rear Diffuser for BMW 6 Series Gran Turismo G32 M Sport (2017-2021, Pre-LCI)

A replacement for the factory plastic rear diffuser on the M Sport bumper of the G32 6 Series Gran Turismo, swapping the black insert for genuine 3x3 weave carbon fiber that matches other carbon parts on the car. It is finished in a double-layer anti-UV clear coat so the sheen holds and the weave does not fade or discolour over time. The factory diffuser unbolts and this one mounts in its place with the self-tapping screws supplied.

The M Sport rear bumper and the pre-facelift body are both required. The supplier data gives the years as both 2017-2020 and 2017-2021, and the facelift arrived during that period, so confirm your car by VIN, or send photos of your rear bumper, before ordering.

Rear sensor note: if your car has a sensor opening or door in the rear bumper area, the sensor may be blocked once this diffuser is fitted. Check before ordering.
