Perrin Gurney Flap for Short Premium Wing - Subaru WRX / STI 08-14

Description

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.

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.
