Just had my wheels bored this weekend to eliminate the 1/4" spacer I was using. The guys at a place called The Wheel Zone on Palm Ave. in South San Diego did it in about an hour. It cost me 100 bucks to do the 350z wheels and that included taking them off the truck, dismounting and remounting the tires and balancing. Since you have the wheels and tires off already, it shouldn't cost too much. Just a suggestion... those wheels you have are too nice to just throw out.
