Generally speaking any 5.10x18 rear will fit. Pick your poison. A lot of us run them in varying brands and patterns. Most of the feedback is subjective at this point, and we don't agree on very many things in here . But I think it's generally agreed that most are better than the stocker offroad.
Never ridden a rear-to-front conversion, but there a few around. The Japanese kits are pretty spendy, most I've seen have been accomplished using BW parts.
