Not Ranked
You're correct that tires should be chosen to be as close in diameter as possible, but within a half-inch, front/rear, is plenty close in most cases. You may need to re-adjust your suspension, rake, ride height etc. and speedo gearing, but such tweaks are always a part of tire changes on a high-performance vehicle.
I think there are more important considerations than absolute tire diameter or a modest front/rear diameter difference. Choose by those considerations and adjust to a diameter change. (All within reason, of course...)
