Rear diffusers are extremely efficient downforce producing devices when designed properly.  We set out to produce a functional rear diffuser for the Porsche 987.1 and 987.2 using state of the art R&D processes.  Utilizing scan data, CAD, and ANSYS Fluent analysis software; we were able to design and produce a functional and aesthetically pleasing rear diffuser for this Porsche chassis.  The three main diffuser planes are produced from 2x2 twill, autoclave cured, carbon fiber; while the strakes are manufactured from a durable polyurethane for longevity.  The entire unit bolts to chassis locations through multiple sheet metal bracketry.  There is absolutely no drilling or fabrication required for installing this rear diffuser.
