Transform the performance and aesthetics of your BMW E46 M3 Coupe with the Karbonius E46 M3 CSL Carbon Roof Panel—a premium structural upgrade engineered for enthusiasts who demand both lightweight performance and factory-level fitment. This high-performance roof panel is a direct replacement for the OEM roof and mirrors the iconic CSL design, delivering weight savings and aggressive styling with uncompromising quality.
Crafted entirely from 100% prepreg carbon fiber and cured in an autoclave, this roof panel ensures exceptional structural rigidity and minimal weight. Weighing only 3.3 kg (approximately 7.2 lbs), it helps shed around 5 kg (approximately 11 lbs) from the car’s highest point—one of the most impactful areas for reducing weight and lowering the center of gravity. This translates to sharper handling, better balance, and improved vehicle dynamics, especially during spirited driving or track use.
The carbon weave is finished in a high-gloss UV-protected varnish, enhancing both durability and the luxurious visual appeal of exposed carbon fiber. Every Karbonius roof is manufactured in-house in Spain under strict ISO 9001 quality management standards by expert technicians. To ensure exclusivity and traceability, each panel is individually numbered.
This CSL-style carbon roof also features integrated drip rail moorings and precise contouring for a seamless fit on all BMW E46 Coupe models, including the M3. Whether you’re looking to elevate your vehicle’s performance, shed weight, or embrace the authentic CSL look, the Karbonius roof delivers a superior solution.
