If you're competing, then the difference in handling caused by using a different tyre on the front than the rear is something a competent driver can readily account for though it might not be optimal for performance. The difference might be dialed out with suspension and pressure adjustments, anyhow.
Is your intention to run this configuration permanently, or only until you can afford to buy a full set?
Only temporarily the rears are at 7/32", once they wear down to 4/32 I would swap them out. It isn't a question of affordability I just don't want to waste away two perfectly good tires. I can't store them so they will most likely be recycled. I plan on doing a few conservative Track and AutoX sessions this spring/summer.
