Well, if you're putting down any serious power you'll be more happy with the wider tires for sure. If you want lower profile, you can definitly find them.
I actually got these wheels from chevelldude and so I don't really know much about them. Search his name and drop him a pm, he's way cool.
The ride height was achieved by only lowering the rear 2'. The front is stock w/ new shocks. Hope this helps. PS. I might be selling these wheels in a couple of weeks if my truck doesn't sell and just go back to the stockers.
