The Karbonius E46 M3 CSL Carbon Front Splitter Set is a direct carbon fiber reproduction of the iconic CSL front splitters — constructed in a 1×1 plain weave to precisely match the texture and appearance of the original OEM components. This set is an identical reproduction of the OEM CSL front splitters, maintaining the same aerodynamic geometry while replacing the factory plastic with motorsport-grade carbon fiber.

The splitter set weighs just 250 grams and is manufactured from 100% prepreg carbon fiber at Karbonius' facility in Spain under ISO 9001 quality management standards. The high-gloss varnish finish provides UV protection and accentuates the 1×1 plain weave. All mounting screws are included for a straightforward, precise installation.

Each piece is individually numbered to guarantee authenticity and origin.
