I'm wanting to run VIP dish rims on my box and i was wondering if any body can tell me whats the lowest offset i can run with a 3 degree camber in the back with a 19" or a 18" rim. If someone could give me an example like this [18x8.5+18 (F) 18x9.5+18(R) with 225/35/18] it would be great. If you can tell me what tire sizes too that would be great.
