Without spacers, definitely will not clear stoptechs. I remember when I tried it with a 3mm spacer, it was really close. I think 5mm will def work, but run some neg camber and use a narrow tire like Falken 452's. For the rear, I think a 10mm spacer should be adequate and maybe stretch a 255 or go with a 265 tire. Again, need to lower car and run neg camber.
