or try the old baseball bat trick to roll your fenders and give you more clearance and/or lose the tailpipes and go with dumps.............I'm assuming you already got rid of the quad shocks of course.............
you can also use a ball peen hammer and a torch and "massage" the inner fender well
I've done that and got a 15x10 with a 6.5 bs on a 90 hatch before
