Rear diffusers are extremely efficient downforce producing devices when designed properly. Verus Engineering 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; they 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.
