APR Performance GTC300 61" Carbon Fiber Wing for 02-07 WRX / STI

APR Performance GTC-300 Adjustable Wing

The GTC-300 Adjustable Wing is a high-efficiency aerodynamic upgrade engineered for motorsport, track-focused, and performance street vehicles. Designed to generate strong downforce with minimal drag, it improves cornering grip, braking stability, and high-speed balance.

Specifications

• Span: 61”(1549mm)
• Chord Depth: 10” – 12” (254mm – 304.8mm)
• Height: Adjustable — Up to 13” (330.2mm)

Key Features

Aerodynamic Airfoil Design
CFD-developed airfoil optimized for efficient downforce production while minimizing drag. The cambered profile improves airflow attachment and rear stability at high speeds. Performance data available upon request.

Fully Adjustable Angle of Attack
Adjustable from 0° to 15° for precise aerodynamic tuning.
• Higher angle = Increased downforce & grip
• Lower angle = Reduced drag & higher top speed

Performance Efficiency
Optimized downforce-to-drag ratio of approximately 8.8:1 — delivering strong rear load without sacrificing straight-line performance.
