robinjoe,
FYI:
Centerline (
www.centerlinewheels.com ) makes wheels that do not require hub-centering rings. Why? Because the wheel you order is made specifically for your hub bore.
A buddy of mine ordered and received the 5-spoke Storm wheels and they are pretty sharp (rotary forged 17 x 7, polished finish) and light (15 lbs per wheel). The wheels cost him $139 each.
