The Karbonius E92 M3 Carbon Roof Panel is a structural replacement for the factory roof on the E92 Coupe, weighing just 3.3 kg — shedding approximately 5 kg compared to the OEM steel roof. Reducing mass at the highest point of the car lowers the center of gravity, the most critical area for handling and dynamic balance. Despite its exceptional lightness, the panel delivers outstanding structural integrity thanks to a multi-layer prepreg carbon fiber laminate schedule.

Manufactured 100% from prepreg carbon fiber and autoclave-cured in Spain under ISO 9001 quality management standards, the roof is produced by qualified staff using a manual process with rigorous quality control at each stage. The high-gloss varnish finish accentuates the carbon fiber weave and includes UV protection — essential for a component permanently exposed to the elements.

Fitted with integrated drop-rail moorings, the roof panel installs using the factory mounting system without modification. Each piece is individually numbered to guarantee origin and authenticity.
