CSL OE+ carbon trunk

Tap right for info.

Same exterior shell, but lighter.

The Karbonius design sheds 6kg over the OEM CSL trunk. This is made possible by pre-preg carbon instead of sheet moulding compound (SMC) BMW M used.

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.

Finish options.

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

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.
Build journal: a special series
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.

In this Special Series, I will document the Karbonius unboxing, fitment and final aesthetics.

Enjoy,

Professional installation is required

At minimum, you will need professional paint services. I highly recommend you let a body shop fully fit the trunk.

It will most likely requires slight triming to the license plate lights, lock and rubber stopper fitting holes.

You will need to drill holes if you intend to fit the CSL trunk liner as well.
