The Karbonius E9X M3 Carbon Rear Wing Stage 2 is the most aggressive aerodynamic option in the Karbonius E9X M3 exterior range. A dual-element design engineered and validated by Karbonius’ in-house team using 2D and 3D aerodynamic analysis, the Stage 2 wing delivers 200 kg of downforce at 250 kph effective for serious track use while adding a bold, race-inspired presence to street vehicles.

The kit pairs full carbon fiber wing elements and endplates with anodized aluminum and carbon fiber uprights, and features a laser-engraved adjustment system that clearly indicates positions for maximum downforce or maximum efficiency. Weighing just 3.2 kg for the complete assembly, it provides outstanding aerodynamic loading without significant mass addition. The same prepreg carbon fiber and autoclave manufacturing process used across all Karbonius products is applied throughout, ensuring the finest available finish and structural integrity.

Each wing is produced in Spain under ISO 9001 quality management standards and individually numbered for authenticity. The Stage 2 wing is also part of the complete Karbonius E92 M3 aerodynamic kit, alongside the Race Front Lip and the Side Skirt Extension Set.
