Purchased 4/20/2016, looks GREAT after being mounted on matte black wheels. It is now 8/2/2017 and there are signs of rust on some of the studs, particularly on the spare wheel. I keep my 2016 Wrangler JKU in my garage, it's not an everyday car so I'm surprised and disappointed that the rust is already showing. I contacted McGard support and they told me I needed to send them pictures of the rust and a copy of the ID that came with the original box (hoping I can find that) so hopefully they can validate their "lifetime warranty".
