Specifications
Part Details:
At speed, the factory STI wing can flex and bounce on its mounts, an annoying rattle at best and a source of added drag and reduced downforce at worst. This Perrin Wing Stabilizer fits between the wing and trunk lid to eliminate that movement entirely, molded from durable black plastic with a tapered airfoil shape that reduces drag and avoids adding wind noise.
Installation is fully reversible, using included 3M VHB adhesive tape rather than drilling into the trunk lid. Sold individually, many owners run two or three for a more aggressive, WRC-inspired look in addition to the functional benefit.
