Perrin Wing Stabilizer 2015-2021 STI

Eliminate wing bounce!  The stock 2015-2021 STI wing flutters and vibrates at speed, which is distracting and annoying.  Fitting perfectly between the upper and lower rear wing, the Perrin wing stabilizer (affectionately called the “Stiffi”) stabilizes and supports your wing, eradicating wing bounce forever. Simply place the stabilizer (or multiple if you desire a truly custom look) between the underside of you upper wing and secure into place using the included 3M VHB adhesive. This makes installation of the stabilizer a solid yet completely reverse-able upgrade. Looks like a professional rally car!

The Perrin wing stabilizer has an airfoil shape, tapering in size from front to back to reduce drag and minimize the possibility of added noise. Molded from black plastic with an OEM-like texture, they look good right out of the box, or can be painted for a color-matched OEM look.

There are three recesses on the underside of the STI wing for the Perrin wing stabilizer to attach to. Use a single stabilizer 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 any large-wing-equipped 2015-2021 STI, or any other VA-chassis car equipped with an STI wing.
