Crafted from pre-preg autoclave-cured dry carbon fiber this set shields your rear wheel arches from rock chips road debris and water spray kicked up by wider tires—especially useful if you’ve upgraded to 20” or larger wheels. The sleek extended contour not only provides extra protection but also adds a subtle motorsport-inspired aesthetic that complements the M3’s aggressive stance.
Each piece is meticulously hand-finished in 3K twill weave carbon fiber for precise fitment and visual uniformity. Installation is simple and takes about 20 minutes for both sides utilizing OEM mounting points—no drilling required.
