1. To have an aggressive street driven car that will see some autocross and track duty (just for fun).
2. Increase turn in/reduce understeer (or at least not increase it)
3. Maintain straight line acceleration

At the time I purchase my new tires, my setup will be as follows:

Stance Coilovers (these may change to APEXi)
Stillen Sway bars (probably set to the softest setting)
Wheels: F: 19x9.5 R: 19x10.5
Tires: Nitto Invo F: 245/40ZR19 R: 275/35ZR19

I am considering changing my tires to:

1. Bridgestone Potenza RE11's F: 245/40R19 R: 285/35R19
2. Bridgestone Potenza RE11's F: 255/35R19 R: 285/35R19

Which would be the best set up to achieve my goals? What type of results can I expect?

Thanks for the guidance all!
You don't think 255/35 aren't too off from circumfrence of factor specs? I was thinking 255/40 would match better. Or have you heard the 255/35 is better?... based on 285/35 circumfrence
