This item has been tested on track as well as refined through Computational Fluid Dynamics (CFD) to provide a significant reduction in lift while reducing drag. CNC laser cut from 5052 aluminum sheetmetal, and then precision bent using CNC press brakes means each part comes out consistent. Designed, analysed, and manufactured in the United States using United States machines and materials.
