The Perrin Wing Stabiliser or Stiffi reduces flex and bounce in your factory Subaru STi rear wing (spoiler) whilst adding a bit of WRC styling.
Fitting perfectly between the wing and boot lid supporting your wing from excessive vibration and vertical movement, eradicating bounce in the wing. Simply place the stabiliser(s) under the wing and secure it using our 3M VHB tape.
Installation of the stabiliser(s) is a solid yet completely reversible upgrade.
The tapering airfoil shape which reduces drag and greatly reduces the possibility of added noise.
Molded from black plastic with an OEM like texture, wing stabilizers look good right out of the box or paint them for a color matched OEM look.
Recommended configurations include using a single stabiliser to eliminate wing bounce all together and two/three stabilizers for an aggressive WRC look.
Configurations of four or more wings can be accomplished with heavy modifications but are not covered in the included instructions.
Direct fit for the Original factory fitted Subaru spoiler fitted to the Blob Eye STi (03-05) & Hawk Eye STi (06-07) models - not designed for aftermarket spoilers. Does not include spoiler itself.Part Ref: PSPBDY100BK
