AutoTecknic Carbon Rear Wheel-Arch Extension Set for G30 / F90 BMW 5 Series and M5
AutoTecknic has developed carbon fiber rear wheel arch extensions for the F90 M5, using the pre-preg dry carbon method to mitigate unsightly damage from small rock chips. These extensions also protect against water puddles and newly paved tar. Additionally, the extensions enhance the vehicle’s appearance, giving it a more trendy look. The installation of these AutoTecknic carbon fiber rear wheel arch extension sets is simple, utilizing the original mounting locations. Crafted by master craftsmen in a 3K twill weave carbon fiber, they ensure perfect aesthetic and fitment. Dry carbon, the highest-quality version of carbon fiber products, is manufactured in a process that includes placing the pre-preg carbon materials into a mold and then curing them in a sealed vacuum (autoclave). This method reduces pinholes and air pockets, minimizes waste, and results in a lighter product compared to the “wet” method. For those adding 20″ or larger wheels, AutoTecknic recommends these trim pieces to prevent spray from the wider rear tires. Suitable for any F90 M5, these extensions not only add a sporty look but also offer slight improvements in stone protection for the rear bumper. Installation can be completed in less than 20 minutes for both sides, with a package that includes a pair of dry carbon fiber splash guards, with rivets being optional for the F90 M5 and F90 M5 Competition.
