Archetype Racing is a custom fabrication shop that specializes in Mustang track and race parts. They partner with Common Fibers to bring customers’ cars up to track and race specs. All of these custom parts start with CAD, and Common Fibers is responsible for getting them all the way to finished, show/track quality pieces rendered in beautiful carbon fiber. This Banshee diffuser took many hours of R&D to perfect; however, the result is quite amazing and is well worth the investment.
