I put a custom posi equipped, super strong Currie built 9" FORD rear end w/disc brakes in my Buick as a result of a damaged rear end and now my wheels don't fit. (Rallye 15X7s with 235-60-15s) I am now faced with having to get new wheels and tires and I am split between going with a 15" tire with the right offset to clear the calipers, or going to 17s or 18s. Seems like one upgrade leads to another...anyway, does anyone have any suggestions? Car is on 2" lowering springs and I kinda want to go for the pro-touring look. Like to have lots of tire under there but the rear wheel well's opening is small. Thanks!
