(2011-2014) Subaru WRX & STI –– Rear Diffuser

  Why We Built This! We wanted a factory-like Diffuser that kept the car driveable, functional, & added to the rear end vs. taking away from the already aggressive body lines. We felt that many ‘Universal’ Diffuser were simply too similar & alike - You need options.  What’s Included? Rear Diffuser Installation Guide  Mounting Hardware (2) Decals Features! Designed, CNC Built & Powder Coated In-House Built From Aircraft Grade Aluminum Professionally Powder Coated Gloss Black Features Rounded Fins for Optimal Drivability + Air Flow OEM Style Installation & Fitment Pre-Drilled Mounting Holes Road Tested & Track Proven at 140+ MPH
