Mines is lowered 40mm on pi springs and with my 17's doesnt rub at all. Only catches occasionally with two ppl in the back. Make sure you have Falken ZE512 205/40/17 tyres and u will be fine. Its a bit of a hit and miss tho, check out
www.zsoc.com if u wana look further into it as sum zetec s' rub and some dont. Best of luck mate.
