The APR Performance GTC-300 Adjustable Wing is a high-performance aerodynamic solution engineered to enhance rear-end stability in motorsports and high-performance street applications. Designed for efficient downforce generation with minimal drag, the GTC-300 improves cornering grip, braking stability, and high-speed balance.

Specifications

• Span: 61” or 67” (1549mm / 1702mm)

• Chord Depth: 10”–12” (254mm – 304.8mm)

• Height: Adjustable up to 13” (330.2mm)

Key Technical Features

CFD-Optimized Airfoil

The GTC-300 features a Computational Fluid Dynamics (CFD) engineered airfoil profile designed to maximize downforce efficiency while minimizing drag. Its cambered shape increases pressure differential across the wing surfaces, improving airflow attachment and reducing separation at high speeds for enhanced rear stability.

Adjustable Angle of Attack (0°–15°)

A fully adjustable angle of attack allows precise aerodynamic tuning:

• Higher angles: Increased rear downforce for improved braking and cornering performance

• Lower angles: Reduced drag for greater straight-line speed

This adjustability enables drivers to tailor performance based on track layout and driving style.

Aerodynamic Efficiency

Engineered to achieve an impressive 8.8:1 downforce-to-drag ratio, the GTC-300 maintains strong rear grip without significantly compromising top-end performance. Ideal for both technical circuits and high-speed tracks.

Downforce & Drag Characteristics

At higher settings, the wing increases vertical load on the rear tires, improving traction and cornering capability. At lower settings, aerodynamic resistance is minimized to support higher top speeds and stronger acceleration.

Carbon Fiber Construction

Manufactured from pre-impregnated woven carbon fiber and autoclave-cured in aluminum billet molds, the GTC-300 provides:

• Excellent strength-to-weight ratio

• High structural rigidity to prevent flex under load

• Long-term durability and resistance to heat and stress

Adjustable Pedestals & Mounting

The wing mounts using 10mm aircraft-grade 6061 billet aluminum risers with angle adjustment capability. This system allows fine-tuning of wing height and positioning to optimize airflow and downforce distribution relative to chassis setup and ride height.

Size & Application

As a mid-to-large sized wing, the GTC-300 strikes a balance between significant aerodynamic performance and manageable drag levels. It is well-suited for:

• Track builds

• Time attack cars

• High-performance street vehicles

Its dimensions allow compatibility across a wide range of performance platforms while delivering measurable aerodynamic gains.
