Specifically designed for the 2004-2007 Subaru WRX & STi fenders

• Developed through pressure and flow testing
• Designed and produced in the USA
• Decreased lift on the front of the car

What you get:

• Precision waterjet aluminum louvers
• Aluminum rivet hardware
• Vinyl cut template

Why vent your fenders?

The rotating tire creates lots of air turbulence and pressure inside your fender. That pressure equals lift! Lift is the enemy of going fast. Reducing lift has the same net effect as adding downforce to your car. Venting your fenders releases that pressure build up in the wheel

Features of the kit

This is a DIY part. That said, we’ve thought about ease of install from the beginning and you get a full vinyl cut template which removes all of the guesswork from your install – just stick it on and it shows you where to cut.

The louvers ship flat (unbent), you bend the fins when you receive them, and you’re free to finish them however you prefer. Powdercoat will have great longevity, but even simple Rustoleum flat black looks fantastic. Another great tip is to go down to your local NAPA and they can paint match to your car’s color and mix it up in a spray can for under $10.
