BMW G80 M3 - Carbon Fiber Rear Wheel Arch Extension Set

Protect and enhance your BMW G80 M3 with the AutoTecknic Dry Carbon Fiber Rear Wheel Arch Extension Set, engineered for both function and style. Every G80 deserves to stay as sharp as the day it left the showroom—and these extensions are designed to do just that.

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.

Dry carbon is the pinnacle of composite manufacturing—produced using a vacuum-sealed autoclave process that eliminates excess resin, air pockets, and pinholes. The result is a component that’s lighter, stronger, and cleaner than conventional wet carbon alternatives.

Whether you’re looking to add functional protection or visual refinement, the AutoTecknic Dry Carbon Rear Wheel Arch Extensions deliver the perfect balance of performance engineering and aesthetic precision.
