OP's car sees track duty about 2/3 of the time, so I assume he's more so sensitive to tire behaviors.
If he's asking to run square tire on his current wheels, then I would think the different "stretchness" may cause a funny feeling, where front tire sidewall is more prone to bend vs the rear. A proper width tire that matches to a 10 in wheel will certainly have a healthy bulge if fitted on a 8.5 in wheel.
