CSL Structural Carbon Roof Kit

Tap right for info.

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.

1x1 CSL matching weave.

Using CSL matching carbon, the roof is made from 1x1 weave and finished in gloss clear.

I've curated all you need to complete the swap.

The roof panel is compatible with Genuine BMW hardware.

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 unboxing, roof swap and final auxiliary hardware installation.
