i lay 20's on stock arms and drop spindles, if you get a narrower rearend and get the rite off set you want have any sliding door issues. i have a 89 chevy 4x4 blazer rearend in mine and im inches away from my sliding track, you can lay it on 22" with stock arms but you have to modify them and i dont like to cut and weld on stocl arms, i didnt remove the subframe to Z it and mine dont sit up hill at all. i have pics on my profile and more on my computer and on my myspace
http://www.myspace.com/tha1customizer you can put a re8 up front if you want 2 but it takes more cutting and bracing on the inside of them frame so they dont twist or bend. if you have any questions holla at me
