I dropped mine with Eibachs. about 1 1/2 in front and about 1 and a 1/4 in rear. I had 18x8 on 235 40 18 and 275 35 18 in the rear on a 18x9 with a little rubbing when I hit a bump in the rear but I had a full tank of gas. I never put anybody in the rear though.....it would move back there.....I bet I could have did a 245 45 or a 255 45 in the front without rubbing.
