Thanks. Yeah,I guess a 5"BS would've been about right but you have to remember that I have aftermarket upper control arms and the taller ball joints so that changes the whole thing. Really, it looked like I would've cleared w/o the spacers if I had stock upper BJs but I might have had some rub on the inside rear of the tire on the frame. So I guess you could say with a 17/40s on the front tire, 5"BS whould be about the most you would want to go.
