Ok first off the vehicle is a Nitro rustler 2.5 with all aftermarket suspension parts.Problem is I can't get any traction in the rear on my local track.So was wondering what tires or suspension setup you guys recommend.The surface is a wierd red sand type material,not like beach sand but pretty sure its a type of sand.I know it turns my shoes red.lol. Any Ideas what be greatly appreciated.Thanks!!!!
