So, I'm stuck with this idea for my new NNBS... It's an extended cab LTZ 4x4. I don't know whether to lower it or level it. If I go the level route, it'll be a 2.5" CCM kit with my stock 20's and 33's of some sort, probably Nitto's. If I go the lower route, a McG's 2/4-5 kit with my stock 20's and stock tires. What do you guys think?
