Thanks for the pics. I currently have 16" Ford Van wheels on the truck, but I'll definately have to check clearances before I do anything. On the subject of wheel studs- I looks as though, they would need to be pressed into the rotor and through the hub. So they are going to need a substantial shoulder area. My concern is with the integrity of the rotor. There isn't alot of material between the holes and the inside edge of the rotor.
