Just to follow up... I purchased that 2013 set of 18" jeep wrangler wheels and put them on my WK. I bought some 1/4" spacers, but turns out I didn't need them. The wheels fit and I haven't had any rubbing issues. The inner sidewalks of the front tires are pretty close to the suspension bolt, but they clear. I will have to order some TPMs eventually. Plan is to bolt on those bilstein 5100 adjustables all around. I'm thinking 2 inches will be the perfect lift. Thanks for your input everyone.
