FS Mustang wheel size

["William J. Petro" <petronix@optonline.net>]

I'm looking for wheels to autox my 00 Mustang GT which will be run in FS.
Anyone have words of wisdom whether I should go with the stock size of 16 x
7.5 or 17 x 8.  I have the 17 x 8 for the street.  I was thinking I might be
better off with the 16s for autox, for faster steering response, less
rotational mass, etc..  I would be loosing out on the half inch width
though.  Anyone also know what size tire is best.  I'll most likely be
running Kumhos.

Thanks in advance for any info.
