Put 2" Rough Country Spacers and MGR caliper covers on today. Heres a few before and after.
Some people seem leery of these because they are not hubcecebtric. But, the gm hub has a big ring that fits on the inside, so I dont think it's a an issue. Torqued everything to 140 and just took it out on freeway at 80mph. Smooth as can be it could be my imagination, but it feels a little less floaty on highway as well.
Mgr caliper covers, I don't feel are worth the 170 price tag. Front fits well, back is a little shaky. And they are like 3mm thick. But they went on anyways. Can only post 1 pic for some reason.
