Mine are 18x9 et 20 on the front with 215/40/18 tyres, not running any spacers with -1 degree of camber. Have had the arches rolled and slightly pulled as they were rubbing a bit when cornering but other than that no problems. They clear the coilovers and only touch the arch liner marginally (which i removed) on full lock. Also relocated the loom to be on the safe side due to the ride height. hope this helps
