Perrin Gurney Flap for Premium Wing

• 2015–2021 Subaru | WRX STI
• 2015–2021 Subaru | WRX

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. Professional flow analysis showed it decreases overall lift while only slightly increasing drag - increasing downforce by 35 lbs. at 75 mph, 62 lbs. at 100 mph, and nearly 100 lbs. at 125 mph.

• Fits 2015-2020 Subaru WRX and WRX STI equipped with the low-profile / premium wing trunk spoiler (legacy range - see notes)
• Constructed from 10g 6061-T6 plate aluminum to eliminate corrosion and rusting
• Semi-gloss black powder-coated finish with white PERRIN logo - looks good with every Subaru color
• Precision laser-cut, slotted holes allow alignment adjustments for a perfect fit
• Small profile leaves rear visibility virtually unchanged; third brake light assembly still sits higher than the gurney flap
• Requires drilling into the existing trunk spoiler; includes rivet nut tool and all mounting hardware
• Part #PSP-BDY-402BK
• 5-year manufacturer warranty
