I'm running wheel spacers now. Getting a well known brand, no ebay or cheapie sets, you should be good. Hub - centric are nice, but like I said, a quality brand will hold up whether it's hub or lug centric. If you're on Instagram you know the big quality name out there right now. If not, DM me and I'll tell you, since he's not a sponsor here, I can't say.
On to the size of them, 2" is a minimum unless you want to cut the factory lug nuts down. So a 1 3/4" set, you will have to trim 1/4" of the factory lugs off to run them.
With mounting them, just torque to spec and recheck after 100 or so miles. If they are torqued correctly you shouldn't have problems. No lock-tight, no glue, nothing like that needed.
Just please please whatever you do, get a quality set.. or you will have worse problems down the road... literally...
