RKP Composites has emerged as an industry leader of top quality US and German-made carbon fiber products, starting with an excellent development history in the E92 market. RKP was responsible for bringing M3 GTS and M3 GT4 racing parts to US M3 owners, and easily made the transition to stylish carbon fiber components for the F10, F82, and now F85 chassis. By working within the confines of the original BMW body lines, RKP was able to create uniquely attractive carbon fiber components that made long-standing carbon manufacturers take note. RKP’s approach to exterior accessories that followed BMW’s own design language quickly set the brand apart from their competitors.
RKP’s rear diffuser for the F85 X5M and F86 X6M was designed to remain congruent with BMW’s design language, adding aggressive fins to the center section of the rear bumper while maintaining the outermost ridge of the factory BMW diffuser so as to appropriately balance the existing body lines with the new fins. The RKP X5M and X6M diffuser uses only existing BMW mounting locations and screws, and requires no modification to the car to install.
The RKP F8x X5M/X6M rear diffuser is constructed from 100% carbon fiber, and is hand-laid in the United States. Each piece is designed for excellent fit and finish, and available in a 1x1 plain or 2x2 twill weave.
