so is bob saying that a 4 inch backspace is used on a 7 inch wide wheel. i'm assuming this is for a 13 inch wheel correct? and fi so can you turn lock to lock without rubbing, with stock suspension and ride hide, stock body, and about the same sidewall height as stock. i'm trying to get a wide wheel without changing the speedometer or ride quality...i know its impossable but i'm trying to stay as close as i can. my reason for staying with 13's, so i can have a taller sidewall still to dampen the ride as this will be a daily driver car. sorry to post this, seems like wheels and tires issues have been beat to death over and over but i just can't find a straight up answer, then again most people dont with this paticular subject.
