Subaru STI 2011-2014 SPEC 61" GTC-300 Carbon Fiber Adjustable Wing

This item is made to order, normal lead time is 1-2 weeks.

The APR Performance GTC-300 Adjustable Wing for the 2011–2014 Subaru STI is a race-engineered aerodynamic component designed to deliver exceptional downforce, stability, and aerodynamic efficiency. Developed using Computational Fluid Dynamics (CFD), the GTC-300 optimizes airflow to achieve superior aerodynamic balance between downforce and drag—ideal for track and high-performance driving applications.

Key Features:

• Carbon Fiber Airfoil Construction:
  Manufactured from pre-impregnated woven carbon fiber using autoclave curing, the GTC-300 offers a lightweight yet rigid structure that resists flexing under high aerodynamic loads.
• Adjustable Angle of Attack (0°–15°):
  Allows fine-tuning of aerodynamic performance for different track conditions. Higher angles provide increased downforce for tight circuits, while lower angles minimize drag for high-speed straights.
• Aerodynamic Efficiency:
  The GTC-300 achieves an 8.8:1 downforce-to-drag ratio, maintaining strong rear-end grip while minimizing drag to preserve top speed and balance.
• High-Strength Mounting System:
  Equipped with 10mm 6061 billet aluminum pedestals for secure and adjustable mounting. The riser system allows control of wing height and positioning to optimize downforce distribution.
• Fully Functional Design:
  Each wing is engineered for real aerodynamic performance—not cosmetic appearance—ensuring consistent airflow management and stability under high-speed conditions.
• Optional Gurney Flap:
  A ½" carbon fiber gurney flap is available to further increase downforce and reduce flow separation during aggressive cornering.

This wing is ideal for Subaru STI (2011–2014) owners seeking improved aerodynamic control for track use or high-performance street setups.
