Carbon fiber is used in racing because of its light weight and strength. Plus it looks really, really cool. This frame is unique in its many features. Hand built using high-quality, 3000 filament carbon fiber; it will look great on your vehicle for years. The quick-change feature is really trick. Simply mount the backing frame and license to your vehicle and the frame pops in place. The screws are covered for a clean look. A rugged polycarbonate window protects your plates from insects and dirt. (Check your local laws, protective license plate shields may be illegal in some states.) Simply press the mounting tabs on each side with the removal tool (included) to remove the frame when it's time for new tabs. Definitely the nicest carbon fiber frame I've found to date and well worth the investment.
