Here is the Scca stock wheel rule:

13.4 WHEELS

"Any type wheel may be used provided it complies with the following:
it is the same width and diameter as standard, and as installed
(including wheel spacers if applicable) it does not have an offset
more than +/- 0.25 inch < about +/- 6mm> from a standard wheel for the car. The resultant change in track dimensions is allowed.

"Wheel spacers are permitted, provided the resultant combination
complies with the offset requirements of this section. Wheel studs,
lug nuts, and/or bolt length may be changed.

"Vehicles equipped with rims having metric specifications may use
alternate rims as determined by using the following procedure:
Diameter: converting the metric measurement to inches and using
the nearest smaller inch diameter rim.

"Width: converting the metric measurement to inches and using
the nearest smaller 1/2-inch width rim. Offset and track must

still comply with the requirements of this section."

The Honda parts manual lists the standard fir wheel as a 14x5 inch (no mention as to offset). The Sport fit wheel is listed as a 15x6 and as we all know has a 55mm offset.

I measured the stock Fit Sport wheel to weigh 42.0 pounds with a 23# Avon tire mounted. So they weigh 19# once you do the math..
