3 things of the top of my head would be
proper back spacing
rolling the fenders
removing the quad shocks
I believe 363coupe runs 10.5 on his notch.I'm sure he will chime in
those three plus you have to massage the inner fenders with a bfh to stop rubbing on extreme cornering. But if you have stock control arms you are gonna rub under hard corners no matter what, there's too much movement...
I ran them on my old ride and will run them again on my new build...
363coupe only runs 17x10s, but with that silly ass beadlock of his its probably out to 10.5, but he's got all said above and full wolfe racecraft suspension, so his rear doesn't move around, lol...
