APR GTC-300 Carbon Adjustable Wing – Subaru STI 2015–2021

Designed exclusively for the Subaru STI (2015–2021), the APR GTC-300 Carbon Fibre Adjustable Wing delivers advanced aerodynamic performance with aggressive styling. Available in 61" and 67" spans and standing 13" tall, this wing features a 3D airfoil shape engineered via Computational Fluid Dynamics (CFD) to optimise airflow — reducing drag while generating effective downforce for superior high-speed stability and cornering grip.

Crafted from lightweight, high-strength pre-preg carbon fibre composite materials, each wing airfoil is produced through high-temperature autoclave and vacuum bagging processes to ensure durability and exceptional strength-to-weight ratios. The wing is supported by 10mm aircraft-grade 6061 billet aluminium pedestals finished in flat black powder coat for a sleek, durable look.

This wing is a serious performance upgrade that fits perfectly over factory spoiler/wing mounting points, making installation straightforward while transforming your STI’s track and street presence.
