Transform the look of your F8x with CT Carbon’s BLAK Series rocker extensions. Finished in a deep high-gloss piano black, these MP-inspired side blades sharpen the profile of your M-car, giving it a lower, wider and more aggressive stance that pairs perfectly with front splitters and rear diffusers.
We’ve fitted these on multiple customer cars at MJ Modifications and the feedback has been excellent. Fitment is spot on, the shine is superb, and the finish looks factory-plus without being over the top.
