I have a sedan with stock suspension, not sport, with 16in type 44s and 205/55 front and rear. What is the maximum width spacer I could fit without rubbing? Also, if I get H&Rs where can I get extended bolts if necesary? I am thinking maybe the 8 or 10mm TMS for the front and the widest possible in the rear for a slightly staggered look. I have searched and not found a real answer, so any help is appreciated. Thanks, Mark.
