The APR Performance GTC-300 is a CFD-engineered adjustable wing delivering premium downforce with minimal drag for BMW M3\/M4 track and performance applications. Fully adjustable angle of attack (0°–15°) lets you dial in the perfect balance for any circuit condition—maximize cornering grip or minimize drag for straight-line speed.

Available in 61\" or 67\" spans with variable chord depth and height options, it integrates seamlessly across both M3 and M4 platforms. Features include vehicle-specific carbon fiber or universal aluminum mounting plates, adjustable pedestals for fine-tuned airflow control, and an optional Gurney Flap for enhanced grip.
