CSL Carbon Trunk (E46 M3)

Tap right for info. Scroll down to order.

A revised interior.

Karbonius replicated the BMW M exterior design of the trunk. The interior was updated with a sleeker inner shell and embossed area to fit an M logo.

Same exterior shell, but lighter.

The pre-preg carbon constructions sheds 6kg over the original CSL trunk made from sheet moulding compound (SMC).

Compatible with Genuine CSL accessories

The badge, lights, locks sections are pre-cut to slightly tighter tolerances than OEM for accessories. This will give leeway to your body shop to adjust.

Ready-to-spray, or clear carbon exterior shell.

The exterior shell is available in primer or cleat coat exterior finish.

Panel gap expectations
The exterior fitment matches an OEM panel without alterations.
Build journal
The first stop to a CSL conversion.

Beyond the material science and its application to BMW M street cars, the CSL marked a new design language.

I find the integrated ducktail'ed trunk embodies this change the most - and is often the most requested CSL conversion product.

In this Special Series, I will document the unboxing, paint, panel gap & accessories fitment along with final aesthetics.

Enjoy,
Matt
