It is the typical trade off between nimble and extra grip. For a street application it really doesn't matter much. Probably impacting buyers more in the pocket book than noticeable improvement for a street car.
In a track environment it is different. Personal preference on what the driver likes will take precedence.
It just depends on if you're needing (in most cases wanting) more grip with wider rubber. Which will in most cases take longer to get up to operating temps.
Also, in regard to small changes in sidewall profile, you're not really going to notice a shorter tire giving you more accel, or a taller giving more top end. It is negligible.
I don't believe you will "ruin" the handling between 215mm and 255mm on a street vehicle. You will certainly feel a difference though. Perhaps a heavy steering feeling and longer transitions from grip to skid. Less predictability and more weight transfer from lateral grip being increased.
If this was a 100hp car with lower c/r it would be a different story. But the FR-S makes adequate power.
