Overview

The UCW Rear Wing significantly increases rear downforce on the GV STI, boosting confidence on track and reducing lap times.

The airfoil was optimized within the available build volume — derived from the V1X — using state-of-the-art analysis software, with CFD confirming the wing receives adequate airflow once installed. In-house scan data gives a near-OEM fit and finish.

Choose aluminum or carbon fiber endplates.

UCW Wings are assembled per order and ship within 5 business days of receipt of order unless otherwise specified.
