Rear Bumpers

Carbon fibre rear bumper diffuser.

Porsche 987 Cayman - 2005 to 2012 (Gen 1 and Gen 2)

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. The assembly blends function and form utilizing carbon fiber, sheet metal, and hard rubber.

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 durable polyurethane for longevity.  

The entire unit bolts to chassis locations through multiple sheet metal brackets. There is absolutely no drilling or fabrication required for installing this rear diffuser.

Finishing what Porsche started, we fill in the void in the 987's underbody. The middle of the vehicle creates drag on automobiles and covering the turbulent areas with flat sheet aluminum reduces this significantly. By feeding the rear diffuser less turbulent air, we are able to increase the diffuser's ability to create downforce as well.

Produced from sheet aluminum and powder-coated a durable black color, they look great and function as intended. Pair this with our rear diffuser to reduce lift and drag simultaneously.

Through CFD, we have estimated the underbody panels reduce the coefficient of drag (cD) by 0.007; or 7 points.
