All of my RTR cars are basically stock with the exception of trued/sanded stock tires and weight added. This allows them to run pretty well on my routed magnetless tracks. The #6 Camaro does have Slot It wheels, tires, and gears. I threw the Womps in as RTR cars because I don't think they fit any category totally. They have 16D motors and silicone-coated tires.
