I know you REALLY gotta look to tell the difference there but there IS a diff between the Mach 1s and Magnum 500s....and the Magnums look 1,000,000,000,000,383 X better. Wheel Vintiques make them by the way. They aren't some BS take offs. To those that notice the difference, its worth it. Those are what SHOULD have came on the Mach 1.
