The carbon roof swap is often the bridge too far for many in their E46 M3 builds.
I get why: this is expensive and structural.
From the myriad of CSL carbon panel roof manufacturers, I picked Karbonius for two obvious reasons: quality and credibility.

This premium process was chosen for its high tensile strength, light weight and aesthetics.
The roof comes in at 3.3 kg and the exterior is finished in 2-component clear-coat.
Using CSL matching carbon, the roof is made from 1x1 weave.
The roof panel is compatible with the peripheral hardware required to complete the install.
Professional installation is required.
Cutting, welding and gluing structural adhesives are needed, and a re-clear might be needed.
