hi, my car is sitting pretty low on coilys, an on 18'' 8.0 et35 dare lp560's wheels, but as you find the wheels on the rear are sitting well too far in the arch, an on the front there still in abit, so just wondering what size spacers people are using!? or is there an easy way to work this out? im guessing its gotta be around 45mm on rear with 20mm up front? iv tried measuring but with the wheel sitting in the arch so much its hard to get an exact measurement, im after this sort of look with the wheel sitting out a little bit, my tires are stretched a little bit also. any help would be appreciated!
