Based on my experience and driving style I had always felt that my F45 suspension had a little too much push.

I added Z06 sways, and although I understand that this theroretically added more understeer, I did not feel there was a significant difference here. The bars did make for significantly better cornering though.

Suprisingly (at least to me) was that lowering the rear of the car by approximately 3/8" made a bigger impact on this. I would not say that the car is as neutral as I would like it to be, but I felt that it improved.

My thought was to move to a square setup to decrease understeer. Is this far too radical for a C5? Would 275mm x 4 cause the rear to be far too loose? Should I consider 285 x 2 and 265 x 2 instead.

Any thoughts would be appreciated.

If your racing in autocross, you have to decide what class your going to run in for starters. Alignment would be the next change I would make. How aggressive do you want it to be? Go for a bigger rear sway-bar. Smaller front. Try different air pressures.
Where does the car understeer? Entry,Mid or Exit. Adjust your driving style. These are some of things I would look into. There's nothing wrong with a square setup either.

You left out a lot of information for us to help. What group are you running with (SCCA,NCCC,NASA.DCSCC, etc.) stock class or a prepared class, street tires or sticky tires, upgrades permitted, and others. Horsepower mods make another difference.
