Have you drivin on them much? I was about to put in an order for a set of wheels but i need to know if they hold up doing 70mph down the freeway for an extended period of time. I dont want to get them to find out i cant even drive to the wheelin spot. Also what kind of backspacing did you get? I want to run at least a 14.5 without rubbing on the spring or having it look like a skate board.
