Perrin Performance Gurney Flap For 2009-2014 WRX Hatchback / 08-14 STI Hatchback

Add an aggressive aesthetic and, in some applications, increase downforce with the PERRIN Gurney Flap.

INCREASE DOWNFORCE AND PERFORMANCE
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. Analysis has shown the PERRIN Gurney Flap increases downforce by 35 lbs. at 75 mph, 62 lbs. at 100 mph, and nearly 100 lbs. at 125 mph

AGGRESSIVE AESTHETIC
The PERRIN Gurney Flap adds aggressive styling to your 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. Make sure to check out more install photos at the bottom of the page

CONSTRUCTION
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

FINISH
Each PERRIN Gurney Flap has a semi-gloss black finish which looks good with every Subaru color. We ensure durability against the elements by using powdercoat paint which can be applied thicker and has a hard finish that is tougher than conventional paint.

INSTALLATION
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 Limited trunk spoiler and the final look is
definitely worth it.
