Perrin Performance Gurney Flap | 2015-2019 Subaru WRX/STI (PSP-BDY-402BK) Perrin Performance

2015-2019 Subaru WRX/STI Gurney Flap by Perrin

The PERRIN Gurney Flap adds aggressive styling to your low-profile trunk spoiler. Without looking too intrusive, the Gurney flap modification adds a small amount of height to your existing spoiler for a clean, clearly modified look.

The PERRIN Gurney Flap is constructed from 10g 6061-T6 plate aluminum to eliminate corrosion and rusting. Precision laser cut, slotted holes allow for alignment adjustments during installation for a perfect fit. The PERRIN Gurney Flap has a small enough profile that rear visibility is virtually unchanged. After installation, the third brake light assembly still sits higher than the gurney flap. Installation of the PERRIN Gurney Flap is easy with our step-by-step instructions and addition of our included threadsert hand tool. The PERRIN Gurney Flap does require drilling into the existing low-profile trunk spoiler and the final look is definitely worth it.

After sending the PERRIN Gurney Flap in for professional flow analysis, it was determined that it decreases overall lift of the car while only slightly increasing drag. This means the aerodynamic efficiency of the system is increased.
