Classic style, modern materials
The CSL trunk has been at the top of my list for The Phoenix Build. I received the trunk in March 2022 and wrote in-depth review on my Build Journal here.
The Karbonius CSL Carbon Fiber Trunk was designed by using the OEM CSL Trunk (41-00-7-895-884) as the basis for its CNC machined aluminum negative mold.
The CSL trunk is made from multi carbon pieces that are bonded together to create the trunk. Each component is made from pre-preg & autoclaved carbon fiber.
There is no fiberglass here. The end result is an OEM+ quality part that weights barely 5.5kg over the 11.5kg of the OEM CSL trunk that was made from Sheet Moulding Compound (SMC) in Italy for BMW M.
The CSL Trunk by Karbonius includes all necessary holes for the installation of OEM accessories: lights, locks, liner, etc.
An updated interior
The exterior design is a 1:1 replica of the original CSL trunk, while the interior has been slightly updated with design touches to make the interior more appealing as more will opt to leave the interior bare carbon instead of body coloured.
The interior carbon fiber is clear coated for a durable and quality finish. If you do not run the CSL liner, there is an embossed section in which you can apply a M logo.
Optional Wing Reinforcement
Karbonius offers the optional to reinforcement the mounting points of the bolt holes of wings. This is only needed for motorsport applications and is not required if you don't plan on bolting a wing to the CSL trunk.
