sleeperGS

I'm not sure if i'm posting this in the correct place but here goes....I plan on lowering my 2nd gen gs with Tien CS coilovers and also installing the rear camber kit.... My question is, with this set up what size rims and offset should I go with. I'm trying to avoid shaving/rolling fenders. I would like to go with a 20x10 on the rear and a 20x8.5-9.5 on the front. Can you guys give me some suggestions.
