What is carbon fiber, and why is it used in automotive modifications?

Carbon fiber is a lightweight and exceptionally strong material composed of carbon atoms in a pattern that creates long, interwoven fibers. In automotive modifications, carbon fiber is prized for its high strength-to-weight ratio, making it ideal for enhancing performance and aesthetics without adding excessive weight. It's used in various components like hoods, spoilers, mirror covers, and interior trims to improve aerodynamics and elevate the overall appearance of BMW cars.
