Overview

The Karbonius E92 M3 Carbon Roof Panel is a structural replacement roof for the BMW E92 Coupe. It weighs only 3.3 kg, which is approximately 5 kg lighter than the OEM steel roof. This reduction in mass at the highest point of the car lowers the center of gravity. The panel is manufactured from 100% prepreg carbon fiber and autoclave-cured in Spain.
Show original supplier description
The Karbonius E92 M3 Carbon Roof Panel is a direct, structural replacement for the factory roof specifically designed for the E92 M3 Coupe. This high-performance component weighs a mere 3.3 kg, resulting in a significant weight saving of approximately 5 kg compared to the original steel roof panel (reducing from ~9 kg to ~4 kg including fittings). By shedding mass from the highest point of the vehicle, the panel effectively lowers the car's center of gravity, which is a critical factor for improving handling dynamics and overall balance. Constructed entirely from 100% prepreg carbon fiber using a multi-layer laminate schedule, this roof panel is autoclave-cured in Spain under strict ISO 9001 quality management standards. The manufacturing process involves meticulous hand layup by qualified technicians, ensuring exceptional structural integrity, dimensional accuracy, and a premium finish. The roof is finished with a high-gloss varnish that features UV protection, enhancing the visual appeal of the carbon fiber weave while safeguarding it from environmental degradation. Each roof panel is individually numbered to guarantee its origin and authenticity. Karbonius Composites backs this product with a 2-year manufacturer warranty. Applications are specific to the BMW E92 M3 Coupe (S65 engine) from model years 2007 to 2013. Professional installation is highly recommended.
