Those wheels are actually pretty sweet. I like the matte finish.

A 0 offset should be perfect. My Chambers have a 0 offset and 4.5 back spacing. They fit perfect and look awesome. Just make sure the center bore opening is big enough (look for wheels that fit Nissan and Toyota and steer clear of the GM wheels with the same bolt pattern). I'm running 16s, and I would think the 18s should have no issues.
