FT-86 SpeedFactory in conjunction with Velox Motorsports have released their rear diffuser to solve issues with rear downforce in the 2013+ Scion FRS and Subaru BRZ. Designed off OEM CAD, it features a near OEM fit and finish. This item has been tested on track as well as refined through Computational Fluid Dynamics (CFD) to provide a significant reduction in lift while reducing drag. CNC laser cut from 5052 aluminum sheetmetal, and then precision bent using CNC press brakes means each part comes out consistent. Designed, analysed, and manufactured in the United States using United States machines and materials.
