Hopefully simple question on tire size

My car takes a 235/305 tire by default. If I were to use a 245 in the front (pretty sure it's not a fitment issue), is that better or worse? It would only give me .2" more tread. The GT3RS has a 245 (albeit on a wider wheel), and the claim there is better turning, though I suspect that is more from the change in offset + width than from the tire.

Point being: is it even worth using a wider front while using the same width/offset?

Yes it would help.

Any idea why Porsche chose 235s?

Also related... if I were to push the wheels out a bit to RS specs, that would change the stagger (I can't move my rears out at all). Any clues as to what that change would do, good or bad?

To make sure it would slightly understeer for most drivers
