Pay tribute to the legacy of the original CSL with a modern twist—introducing the V-CSL Aero Rear Diffuser by Vorsteiner for the BMW E46 M3. Inspired by the lightweight performance ethos of the E46 M3 CSL, this diffuser enhances rear-end styling and airflow while staying true to the car’s iconic silhouette.

Crafted from aerospace-grade pre-preg carbon fiber and cured via autoclave, the V-CSL Rear Diffuser features subtle fin detailing and a contoured shape that integrates seamlessly with the factory rear bumper or CSL-style conversions.

Key Features:

  • Designed specifically for the BMW E46 M3

  • CSL-inspired styling with refined aerodynamic contours

  • Improves rear airflow and adds motorsport-inspired aggression

  • Manufactured from autoclave-cured pre-preg carbon fiber for strength and minimal weight

  • UV-resistant high-gloss clear coat ensures long-term durability and carbon clarity

  • Direct bolt-on fitment—compatible with OEM or CSL-style rear bumpers

  • Complements other Vorsteiner V-CSL or V20 Aero components for a cohesive build
