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.
