Perrin Stiffi Spoilers

Add the Perrin Performance STi Wing Stiffi to your ride and eradicate that wing from bouncing forever. Perrin's Wing Stiffi fits perfectly between the upper and lower wing to create a support for the center of the wing. Add a up to 5 sets for a truly unique WRC look. This is Perrin's new version 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, we have given it an actual wing profile. This creates much less drag, and noise than the older version.

Eliminate Wing Bounce
Fitting perfectly between the upper and lower rear wing, PERRIN Stiffis stabilize and support your wing eradicating wing bounce forever. Simply place between the underside of you upper wing and secure into place using our 3M high tach adhesive. This makes installation of our Stiffi a solid yet completely reverse-able upgrade.

The PERRIN Wing Stiffi has and 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 Stiffi's 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.

807/06/2010STiDefinately gives the wrc look. Installation was simple enough. I referenced a video perrin put out on youtube that was very helpful. Fitment isn't perfect but still looks great and is very sturdy. I installed three stiffy's. If you tried to install 5, the outside ones probably wouldn't fit on the bottom of the spoiler properly.
