CSL Carbon Roof

Build journal: A Special series
The CSL'ification of The Phoenix
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.
In this Special Series, I document the entire CSL'ification of The Phoenix, including the CSL roof transformation.
Cheers,
Improved chassis rigidity and aesthetics.
The pre-preg & autoclave'd carbon process was chosen for its high tensile strength and light weight. The roof comes in at 3.3 kg.
OEM Fitment.
I've done the swap. It's OEM level.
I've curated all you need to complete the swap.
The roof panel is compatible with Genuine BMW hardware.
1x1 CSL matching weave.
Using CSL matching carbon, the roof is made from 1x1 weave and finished in gloss clear.
