Add the PERRIN Performance STi Wing Stiffi to your ride and eradicate that wing from bouncing forever. The Perrin Wing Stiffi fits perfectly between the upper and lower wing to create a support for the center of the wing. Add a up to 3 sets for a truly unique WRC look.
The latest version is made of black plastic and has an actual wing profile. This is a significant improvement over the older CNC aluminum version, as it is much lighter and much less expensive. Because Perrin is not held up by machining processes to create this part, they have given it an actual wing profile. This creates much less drag and noise than the older version.
