No problems with mixed tyres on both race track and road. Just make sure the rear is not more grippy (sporty) than the front and you're good to go. E.g. don't mix touring Z8 front with M5/M7 rear, but opposite combo is sweet - long lasting touring rear Z8 and grippy M5 up front. The rear will always start slipping earlier, but the front will stay planted so you're in control.
Mixing same type, like PR3, or 4, with M5 or M7 can be done any way you want, without problems.

Most things done in a hurry need to be done again - patiently.
