Wing Stabilizer for Subaru STI 2015-2018 Plastic Stiffi Support in Black ABS Plastic
Enhance the stability and stance of your Subaru STI with the PQY Subaru STI Wing Stiffi Stabilizer for 2015–2018 models. Crafted in durable black ABS plastic and proudly engraved with the PQY logo, this wing stabilizer is designed to sit between the upper and lower rear wing. Its aerodynamic airfoil shape tapers from front to back, helping to reduce drag while preventing wing bounce at speed. No drilling or cutting is required—install quickly and cleanly with the supplied double-sided adhesive tapes for a sturdy, reversible upgrade that sharpens both performance and style.
Main Description
Designed specifically for the Subaru STI 2015–2018, the Wing Stiffi stabilizer provides a secure tail-fix that stops wing flutter under acceleration or gusty conditions. The black ABS construction and precise form ensure a seamless look that blends with the factory spoiler while giving your car an aggressive, rally-inspired edge. Installation is straightforward: simply attach between the underside of the upper wing using the included 3nn double adhesive tapes—no tools or modifications required. For a truly custom appearance, you can install one, two, or even three Stiffis to tailor the look to your preference. This is a practical upgrade that balances performance with aesthetics, offering a cleaner silhouette and improved wing stability overall.
