Carbon Fiber and Fiberglass Trunks and Rear Decklids
Do carbon fiber or fiberglass trunks and rear decklids make a difference? Yes. The weight reduction helps with performance and fuel economy. Some functional trunks and rear decklids can even add downforce. The weight savings with carbon fiber is even more than fiberglass.
Are carbon fiber and fiberglass trunks and rear decklids safe? Carbon fiber and fiberglass trunks and rear decklids are strong and durable, and function like a normal OEM part. However, you need to make sure that the inner structure (underside) of the trunk or rear decklid is designed to fold or crumple in the event of a rear impact.
