Tuning-shop RKP created a carbon fiber rear diffuser which perfectly matches, not only the rear-end design of the new M3/M4 but also the beautiful Yas Marina Blue color.
The aftermarket RKP diffuser was designed with full length fins that reach all the way from the inside of the insert to their termination point at the rear of the bumper. The fins are particularly thin, and although this makes them especially difficult to manufacture, their appearance is more purposeful and athletic. Unlike the BMW performance diffuser, RKP’s fins extend all the way to the edge of the diffuser, giving them a much more noticeable look in all of the right areas.
