I would think one of the major advantages to going with a smaller wheel are actually the smaller tires.

Weight further out from the center has a greater affect on performance and sticky rubber tends to get pretty heavy as the diameter goes up...

It depends on your purpose.
With a smaller wheel you run the issue you need a larger side wall thus adding to the weight of your overall wheel/tire setup. Now if this is a pure track setup with no street function then that idea can be thrown out.

Good point. I guess I meant if you want to go with an overall slightly smaller diameter. That would still work fine on the street, just the speedo would be a wee bit off...
