The Karbonius G82 M4 CSL Carbon Rear Seat Delete Closeout Kit is purpose-engineered for the BMW M4 CSL — delivering a motorsport-grade interior transformation with the weight reduction, clean aesthetic, and functional rear space that track-focused drivers demand. Precision-molded to the CSL cabin geometry, the four-piece carbon closeout set eliminates the rear seating area and replaces it with a seamless, race-ready finish.
Each kit is manufactured in Spain using pre-preg carbon fiber, factory serialized and production-dated for full traceability. The installation uses OEM hardware and mounting points throughout — making the modification fully reversible if you choose to return the vehicle to stock configuration.
For standard non-CSL M4 fitment, see the Karbonius G82 M4 Carbon Rear Seat Delete Closeout Kit.
