Product Details

Finishing what Porsche started, we fill in the void in the 981's underbody.  The middle of the vehicle creates drag on automobiles and covering the turbulent areas with flat sheet aluminum reduces this significantly.  Produced from sheet aluminum and powdercoated a durable black, 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 0.07; or 7 points.

About Verus Engineering 

Why Verus (pronounced Veh-rus)?  Verus is Latin for true or complete.  We strongly believe in engineering as a whole.  We are also a company comprised primarily of engineers.  We wanted to bring our passion for engineering to our name.

In 2014, a group of Motorsports engineers joined together and began a journey into revolutionizing the components available to the aftermarket industry.  The group of engineers comprised in Verus Engineering have a wide range of previous and ongoing knowledge within the Motorsports world.  We have worked within IndyCar teams and the sanctioning body, NASCAR teams, World Endurance Car (WEC) teams, as leading suppliers to the Motorsports industry, and in leading aftermarket companies as well.  This vast experience allows us to cater to many needs within the automotive industry.  With thoroughly engineered components including the use of Finite Element Analysis (FEA), thermodynamics, heat transfer, and Computational Fluid Dynamics (CFD), we strive to produce aftermarket parts that can outperform the factory components.
