The difference is the shape of the outer lip as well as a different center section. Also lip size and much wider widths available. You can also have the spokes polished or matt gray. They can be made up to 12" widths with any backspace. It will be awesome to see just how much tire can be stuffed...
I would also love to see one done with torq thrust II's or Shelby razor wheels. Can't wait to see one in person! I here there's room for wider tires also. I will probably have American racing make a custom set of torq thrusts for me if the 20" will clear the PP brakes. Also has to have a cammed...
