Downgrading from 19" wheels - Performance loss/gains?

Im currently running VMR V801's in 19x8.5 +35 and 19x9.5 +35 with 255/35/19 and 275/35/19 (This is what the previous owner was running so I kept it on, yes understand the M3 fitment is messing with my gearing and probably sapping my acceleration and fuel economy).

Im looking for max performance out of my e90 325i RWD sedan w/ n52b25 pre lci, specifically more acceleration and sharper cornering.

- What would be the best route?
- Should I downgrade to 18 or 17 inch wheels?
- Should I go for a 225 or a 255 square setup?
- Will increasing the sidewall height reduce that sharper cornering that Im
looking for?
- Should I just change the tyres to 235/35/19 + 265/30/19?
- Does my 325i need more than a 225 square?
- Will a 225 square feel more nimble/sharper than a 255 square?

Thanks for putting up with this, Im grateful for any answers.
