Bullitt Wheels - How to open up bore?

Thank you for all the replies. Yes, the machine shops are pricey. I am getting the same prices. Even at half that, it defeats the purpose of getting bargain wheels. The center of the wheels measure about 2.75 and with my mics on the disk rotor hub, I need about 2.85 or so about 100 thou. I never thought about a stepped bit that big. That is a great idea and will help it stay centered.
