These parts are specifically manufactured for motorsport usage. They are entirely CNC machined from billlet T6-6061 aircraft grade aluminum, have a built in Anti-Lift geometry correction in the design and use proper motorsport bearings. Hardware is stainless steel 304 for corrosion resistance and longevity for use within the harsh motorsport environment.
*We strongly recommend seam welding all the panels 1/2in every 2 inches in that area. Standard prep for a gravel car. See picture below*
