Redesigned back wing mount for the independent wing mount system. A corner graphite wing mount has multiple jobs which enable higher or reduced mounting associated with back wing to adjust to traction, conditions, and racing areas. Whenever traction is quite low mainly on asphalt areas the top of holes enable a greater wing mounting place to generate more stability and traction off-power. When traction is quite high mainly on carpet surfaces the lower holes allow a lesser wing mounting place to diminish traction rolling and also make the vehicle simpler to drive. Machined from premium 2.5mm graphite product.
