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 your upper wing and secure into place using 3M high tach adhesive. This makes the installation of a Stiffi a solid yet completely reverse-able upgrade.

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 3 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 3 for a truly unique WRC look.
