A truly functional rear diffuser designed and built around fundamentals, tested theory, and experience. Specifically engineered to fit the 2013+ Subaru BRZ, Scion FR-S, and Toyota GT-86 without and modification to existing body components. The diffuser attaches to the frame of the car utilizing the existing rear sway bar mounts, Subaru OEM bumper clips and body panel screws. It has been tested on street and track, up to speeds of 140mph+ and during grueling daily driving in mixed conditions. During testing, the diffuser had the structural strength to hold 165lbs of human standing on its weakest point attached to the car without any failure.
Unlike other “diffusers” on the market this is a functioning aerodynamic item and not just an aesthetic rear valance. Absolutely no bumper modification required.
Aero Balance Shifted Rearward.
Adjustable lead edge makes for a tunable diffuser angle.
Type 3 Design features a more aggressive extension behind the vehicle, and a raised center section to maximize performance.
