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

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.
