i have a 9.5in notch out back and i have no problem layin a 30.5in tall tire with a few inches left over in the notch, and i didn't have to cut down my rear end
the problem with stock arms up front is the uca isn't long enuff, so it neg cams alot to lay a 24 and u hit the stock booster, so the hydro booster isn't as wide so thats what most people switch out to
i fliped my stock uca to the underside of the stock spindle, and by doing so it makes the stock uca longer when its dropped all the way, so i can use my stock booster still, i have some 24x9's and they tuck no problems with a 275/30/24 tire, i just roll with my stock 16's almost all the time because summer time is when they are rebuilding the roads around here and winter snows like crazy
