Like Frank, I don't think you will beat the Moon wheel covers. There are design limitations as to what dimensional changes you can make to street vehicle wheels. I'd select a decent alloy wheel onto which you can mount the screw mount Moons. The snap-on versions have been known to fall off on potholes.

If you want to go hog wild, then buy the lightest alloy wheel you can find, probably Centerline, to reduce the rotating mass. But you probably won't notice the difference, so I'd stick with a modestly priced midweight wheel and put the Moons on. For that matter, you could just buy an extra set of the stock steel wheels and drill those for the Moons.
