Eliminate wing bounce! The stock 2011-2014 STI wing flutters and vibrates at speed, which is distracting and annoying. Fitting perfectly between the upper and lower rear wing, Perrin Stiffis stabilize and support your wing, eradicating wing bounce forever. Simply place the Stiffi (or multiple if you desire a truly custom look) between the underside of you upper wing and secure into place using our 3M high tach adhesive. This makes installation of the Stiffi a solid yet completely reverse-able upgrade. Looks like a professional rally car!
The PERRIN Wing Stiffi has an airfoil shape, tapering in size from front to back reducing drag, and eliminating the possibility of added noise. Molded from black plastic with an OEM like texture, Wing Stiffis look good right out of the box or paint them for a color matched OEM look.
There are three recesses on the underside of the STI wing for the PERRIN Wing Stiffi to attach to. Use a single Stiffi to eliminate bounce. Use two for a sportier more aggressive look or use three for a truly unique WRC look.
Covered by Perrin's five-year warranty. Fits 2011-2014 STI (except Limited, which has no rear wing), or any other GV-chassis car equipped with an STI wing.
