Small rock chips can cause unsightly damage to your beloved F90 M5. AutoTecknic has specifically made the carbon fiber rear wheel arch extensions in the pre-preg dry carbon method to prevent unavoidable damage caused by minor rock chips and guard against water puddles and newly paved tar on the road. Not to mention that the extension on the rear wheel arches looks more trendy. These AutoTecknic carbon fiber rear wheel arch extension sets utilize the original mounting location. They are skillfully made in 3K twill weave carbon fiber by our master craftsman for the perfect aesthetic and fitment.

Dry carbon is the highest-quality version of carbon fiber products that are produced. Dry carbon fiber's name also comes from its manufacturing process. Dry carbon fiber is formed using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed vacuum (autoclave) to cure appropriately. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. This method creates the least amount of waste and forms a lighter version of carbon than the "wet" method.

If you're adding 20" or larger wheels, AutoTecknic recommends adding these trim pieces to avoid the spray from the wider rear tires. It can be added to any F90 M5 for a sporty look and provides a minor improvement in stone protection for the rear bumper.

Installation is straightforward and will take no longer than 20 min for both sides. The package includes a pair of dry carbon fiber splash guards, and the rivets are optional for the F90 M5 and F90 M5 Competition.
