APR Performance Carbon Fiber GTC-300 Adjustable Wing for BMW G80 M3/ G82 M4 2021+
The APR Performance GTC-300 Adjustable Wing for the BMW M3 and BMW M4 is built for drivers who care about real aerodynamic performance. This GT-style rear wing helps improve downforce for better grip at speed. You get more stability in corners, more control under braking, and more confidence on track days. Fitment suits the BMW platform and installs as a purpose-built upgrade, not an afterthought.
APR Performance designs the GTC-300 for serious street builds and motorsports use. The adjustable design lets you fine tune angle and balance to match your setup. This wing suits drivers who want functional aero, proven results, and a look that matches the performance of the BMW G80 and G82.
Airfoil design tuned with CFD:
- The airfoil shape uses Computational Fluid Dynamics to improve rear stability and reduce unwanted turbulence.
- The cambered profile keeps airflow attached at speed and limits flow separation.
- You get predictable grip during high speed cornering. CFD data is available on request.
Adjustable angle of attack from 0 to 15 degrees:
- You can tune the wing to match your setup and track.
- Higher angles increase downforce for better braking and corner exit.
- Lower angles reduce drag for higher top speed on long straights.
- You control the balance based on conditions and driving style.
High aerodynamic efficiency:
- The GTC-300 achieves an 8.8 to 1 downforce to drag ratio. This lets you add stability while preserving speed.
- Drivers can adjust settings between sessions to suit tight circuits or fast layouts.
- Lift vs drag coefficient data supports the performance claims.
Downforce and drag behavior you can feel:
- At higher settings, the wing increases load on the rear tires and improves traction.
- At lower settings, the wing reduces aerodynamic resistance and helps top end performance.
- This flexibility makes it useful across many vehicle types and use cases.
Pre-preg carbon fiber construction:
- The wing uses pre-impregnated woven carbon fiber for low weight and high rigidity.
- This helps prevent flex at speed and keeps aero performance consistent.
- Autoclave curing in aluminum billet molds improves material density and long term durability under heat and stress.
Adjustable pedestals and mounting hardware:
- The wing mounts on angle adjustable risers machined from 10mm 6061 billet aluminum.
- You can fine tune height and position to control airflow and balance.
- This setup supports precise aero tuning across different ride heights and track conditions.
Compact size with real performance:
- The GTC-300 sits between small street wings and large race wings.
- It suits cars that need functional aero without the visual bulk of oversized wings.
- It integrates well on many platforms while still delivering meaningful gains.
Vehicle fitment and customization:
- The wing supports vehicle specific and universal fitment.
- APR Performance offers fitment kits for secure installation on most performance vehicles.
- Carbon fiber bottom plates support vehicle specific installs.
- Aluminum bottom plates support universal installs.
- Best suited for mid to large performance cars and track focused builds.
Optional carbon fiber Gurney flap:
- The optional Gurney flap mounts to the trailing edge to increase downforce and improve airflow behavior.
- It supports higher grip in fast corners.
- Height is 1/2 inch or 12.70mm.
- Construction uses pre-impregnated woven carbon fiber.
- Attachment uses 3M VHB double sided tape.
