performance lost? tire size

Would I be able to really feel the performance lost going from a tire that is 235 to 215 as a daily driver? I never go on the track but I definitely do like to accelerate and take nice turns.

Really depends on the tire you are running and plan to run. Example, 235 all-seasons for 215 summers...

I would be running the falken fk452 all summer ultra high performance.

It's kind of tough to say since it's dependent on a few variables. For everyday driving you probably wouldn't notice much of a difference but I think if you were pushing the car hard you would.

I say take the middle of the road option and stick with 225,
and because its a more common size you should get more competitive pricing.

You can't always have your cake and eat it too ..
with 235 you get more grip and loose on fuel economy as a daily driver,
and with 215 you loose a bit of grip and gain a bit on fuel economy...

At worst you might loose/gain 1-2 mpgs and thats being light footed..
I say go with 225 Summers once your current set wear out
