BTW, the November 2013 FastTrack has this Street Category update ...

13.4 WHEELS
Any type wheel may be used provided it complies with the following:
1. It is the same width as standard, and as installed it does not have an offset more than ±¼” from the standard wheel for the car. The resultant change in track dimensions is allowed.
2. Wheel diameters may be increased or decreased 1” from the standard part.

Wheel spacers are permitted, provided the resultant combination complies with the offset requirements of this section. On vehicles supplied with an OE wheel spacer, the wheel spacer shall be considered as a part of the wheel. Wheel studs, lug nuts, valve stems (including pressure-relief types), and/or bolt length may be changed. Tire pressure monitoring sensors (TPMS) may be removed.

Centerlock / Spline Drive / Knockoff type hubs may be converted to lug type hubs, provided the resultant combination complies with the offset requirements of this section
I haven't yet investigated what wheel options that opens up.
