BMW E46 3-Series / M3 GTC-300 Carbon Fiber Adjustable Wing

This item is made to order, normal lead time is 2-3 weeks.

The APR Performance GTC-300 Carbon Fiber Adjustable Wing for the BMW E46 3-Series and M3 delivers professional-grade aerodynamics for track and performance applications. Developed through Computational Fluid Dynamics (CFD), this wing provides exceptional downforce efficiency (8.8:1 downforce-to-drag ratio), offering improved cornering grip, braking stability, and high-speed balance.

Featuring a cambered 3D airfoil profile, the GTC-300 generates high rear-end downforce while maintaining minimal drag. Its adjustable angle of attack (0°–15°) allows precise tuning for different driving or circuit conditions—achieving maximum grip for technical tracks or reduced resistance for long straights.

Constructed from pre-preg woven carbon fiber, the wing is autoclave-cured in billet aluminum molds, ensuring superior rigidity, strength, and a lightweight structure that resists flex under aerodynamic load. The 10mm aircraft-grade 6061 billet aluminum pedestals allow for height and angle adjustments, providing flexible aerodynamic setup and secure mounting.

Perfectly suited for E46 platforms, the GTC-300 enhances aerodynamic stability and styling—ideal for time attack builds, track-prepped M3s, or aggressive street setups seeking functional performance.

Features:

• CFD-Engineered Airfoil Design – Optimized for high-efficiency downforce and reduced aerodynamic drag.
• Adjustable Angle of Attack (0°–15°) – Enables precise aerodynamic tuning for varying track and street conditions.
• High Downforce Efficiency (8.8:1 Ratio) – Maintains superior cornering stability and braking performance.
• Pre-Preg Carbon Fiber Construction – Lightweight, rigid, and built for high-speed aerodynamic stability.
• Autoclave-Cured Manufacturing – Ensures maximum material density, durability, and finish quality.
• Aircraft-Grade Aluminum Pedestals – 10mm 6061 billet mounts provide secure, height-adjustable installation.
• Compact Mid-Size Design – Ideal balance between performance downforce and everyday usability.
• Optional Carbon Fiber Gurney Flap – Adds downforce and reduces airflow separation (½” height, 3M VHB attachment).
• Universal or Vehicle-Specific Fitment – Available with carbon fiber or aluminum bottom plates.
