Description

Karbonius Structural Carbon Fibre Roof – BMW E46 Coupe

Redefine performance and aesthetics with the Karbonius Structural Roof for the BMW E46 Coupe. Crafted from 100% prepreg carbon fibre and cured in an autoclave at our ISO 9001-certified facility in Spain, this is not just a visual upgrade — it’s a serious weight-saving solution designed for performance-focused enthusiasts.

Weighing only 3.3 kg, this full replacement roof (not a skin or overlay) helps shed up to 5 kg from the vehicle’s highest point — a critical location for reducing your centre of gravity and improving handling. Constructed with multiple layers of 1×1 weave (plain) carbon fibre, the roof combines extreme lightness with impressive structural strength.

Finished in a high-gloss UV-resistant lacquer, it offers both lasting durability and an unmistakably premium look, making it suitable for both street and motorsport builds.
