Prototype Nascar wing end-plate. This authentic Nascar cup series car part is from the R&D testing team at Joe Gibbs Racing, and was designed for the debut of the "Car of Tomorrow," for Nascar. Made entirely of carbon fiber, so it's extremely lightweight. Includes part numbers on the back as well. Great condition, has some light scratches on the surface. T-shirts are not included. #racing #vintage #nascar #motorsports #y2k
