I just installed 15 inch American Outlaw Deputy wheels on a 2011 jk Sport. The tires are 33x12.5. With it, I installed the teraflex 2inch level. Unfortunately, after a brief test drive it is apparent the calipers slightly touch the inside of the wheel at certain points in the rotation. I was wondering what the most effective way to go about fixing this issue would be.
You may run into even bigger issues when you need to do new pads, depending on the design of the inner wheel. I would look at going up to a 16" personally. Jeep didn't put 15" wheels on at the factory for a reason. its too tight a clearance, mud, dirt gravel will be a issue for sure.
