Perrin 2015 WRX/STi w/ Premium Wing Gurney Flap - PSP-BDY-402BK

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.

Construction & Finish. The PERRIN Gurney Flap is made from 10g 6061-T6 aluminum with precision slotted holes for perfect alignment and a semi-gloss black powder-coated finish for lasting durability. Its corrosion-resistant design complements every Subaru color while providing superior protection against the elements.

Increase Downforce & Performance. 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.
