BMW F22 Racing M Performance Rear Diffuser
BMW M Performance Diffusor
Genuine BMW Part.
In addition to the standard M235i M-Sport front bumper, the Racing model uses all of the M Performance trim - front splitter, rear diffusor, rear trunklid lip spoiler (Evo rear wing also available), gloss black kidney grilles, and carbon fiber mirror covers.
The M Performance spoilers and diffuser have been designed together to move air efficiently around the body, direct air to the oil coolers in the front bumper, reduce aerodynamic lift and add downforce at high speeds. The M-Sport front and rear bumpers are required (standard on the M235i). Trim pieces like the grilles and mirror covers just look racy and purposeful.
