Only one unit available. Karbonius roof manufactured in exclusive TeXtreme® carbon fiber for the BMW E46 Coupé. A unique opportunity for those seeking maximum weight savings, increased rigidity, and a premium carbon fiber finish. Brand-new product, ready for immediate delivery.
The Karbonius CSL Carbon Roof for BMW M3 E46 Coupe is one of the most effective modifications for reducing weight and improving the vehicle’s dynamic performance. Manufactured entirely from pre-impregnated carbon fiber (prepreg) and cured in an autoclave oven, it allows for weight reduction at the highest point of the bodywork, lowering the center of gravity and improving the vehicle’s response during weight transfers, braking, and cornering.
Each unit is produced at our facilities in A Coruña (Spain) under ISO 9001 quality standards and by highly specialized personnel, guaranteeing excellent finish quality, dimensional precision, and structural strength.
With an approximate weight of only 3.3 kg, it represents a reduction of over 5 kg compared to the original steel roof, achieving a dynamic benefit far superior to that of other equivalent weight modifications located in lower areas of the vehicle.
Despite its extreme lightness, the roof incorporates multiple layers of carbon fiber to ensure high structural strength. Its high-gloss finish with UV protection highlights the carbon weave and provides an appearance inspired by the legendary BMW M3 CSL.
Important: This product is a complete structural roof intended to replace the vehicle’s original panel. It is not a decorative sheet or a part to be adhered over the existing roof.
Manufactured in Plain Weave (1×1) fabric, it also incorporates integrated rain gutter anchors to facilitate professional installation.
Like all Karbonius parts, each unit is individually numbered and includes a certificate of authenticity.
