I feel like the car pushes too much right now and that a little more tire up front might help. I would not want less tire on the rear as I can overepower the rears now.

This would be for DE events on a Boxster S.

You could run either 245 or 255s on the front. Running square allows 4 wheel rotation so you can make the most out of your tire budget though. Some fast Boxsters in SoCal run 245/275 on 8.5 & 9.5 wheels to good effect.
