The Karbonius E92 M3 Carbon Vented Fender Set provides a rapid and effective method to reduce weight and enhance both the aerodynamics and visual character of the E92 M3. Inspired by the Porsche 991 GT3 RS aesthetic — a radical concept for a road car when first introduced — the vented design integrates naturally with any track-focused E92 M3 build while maintaining OEM exterior dimensions.
Integrated carbon vented louvers evacuate the air pressure that accumulates in the wheel arch during high-speed driving, reducing lift and increasing front-end downforce. The Karbonius E92 fenders maintain OEM dimensions throughout, ensuring that factory bumpers and trim fit without modification while delivering the aerodynamic and visual upgrade.
Each fender is manufactured from 100% prepreg carbon fiber, autoclave-cured at Karbonius' facility in Spain, with mounting points produced by Selective Laser Sintering (SLS) in polyamide — a process that delivers superior strength and dimensional accuracy at every fastening point. At just 1.3 kg per fender, the set provides meaningful weight reduction over the factory steel units. Every piece is individually numbered for authenticity.
