Ensure the stability and period-correct accuracy of your aero package with this authentic BMW 3.0 CSL "Batmobile" rear wing centre fin. Designed as a direct evolution of the early Group 2 setup, this central support was introduced to eliminate wing flex and provide essential structural reinforcement at high speeds.

Product Specs

• Material: High-strength, lightweight reinforced Fibreglass (GRP)
• Compatibility: BMW E9 3.0 CSL "Batmobile" rear wing assemblies
• Design: Late-specification Group 2 vertical support fin
• Finish: Supplied in a smooth gel coat, ready for final prep and paint

Why Choose the Centre Fin?

• Enhanced Stability: Prevents high-speed vibration and "buffeting" of the rear wing blade, ensuring consistent downforce across the entire span.
• Historical Accuracy: A vital component for owners looking to replicate the later, evolved Group 2 competition cars that dominated the circuit.
• Structural Support: Distributes aerodynamic loads more evenly across the bootlid and wing structure, reducing stress on the outer mounts.
• Race-Ready Build: Manufactured to meet the rigours of historic motorsport while maintaining the iconic CSL silhouette.

Installation Tip: This support fin is positioned centrally between the bootlid and the main wing blade. We recommend a careful dry-fit to ensure the wing remains perfectly level before final drilling and securing.

Lead Time: This component is Made to Order. Please contact us for current production schedules
