IF you talk to any Customer wheel builder .. EX: Stockton... they will tell you that you do not need to make any CENTER WHEEL HUB to rotor contact .. the studs is what centers the wheel when bolted down to rotor face ... How much material needs to be removed to give you the clearance you need ?
Stockton Wheel can eat my ***. If the center hub size is not important, why does every automaker design them to have a snug fit to the wheels? This is known as "Hub Centric".
Again, it is the center hub register that centers the wheels. The lugs retain the wheel.
Yes, I have used wheels with a large hub hole that only use the lugs and nuts to locate the wheel. These are known as "Lug Centric". Yes, they do work but you are giving up a great feature by using them.
Also, the Mopar big bolt pattern used a hub size of 2.81 inches, slightly less than 2.875" which is 2 7/8."
