Mirrors sit at eye level on the angle most people see your car from — walking up to it in a parking lot. Factory plastic shouldn't be what registers first.
Carbon mirror covers and caps for the BMW M3/M4, M2 and M5, and the Chevrolet Corvette C8. Several are complete replacement units rather than shells bonded over the factory housing — each listing says which. Sold as matched pairs, driver and passenger side, finished together so the weave and gloss agree left to right.
A mirror housing is a compound-curved shell with no flat reference anywhere on it, viewed from inches away. Any difference between left and right is on display every time you check a mirror.
