Congrats on the wheels man! Whats the offset? For ease of fitment 225/40 is a great size but you can definitely bump to a 245 with all that power you've got. I think a high performance 235 width is probably not a bad idea though. Split the difference. A better tire in a smaller size will outperform a cheap tire.

What's your tire budget? Are you going to get winter tires on your stock rims and run some really nice summer tires on the new ones?

I think the closest tire size from your original 215/45/17 is going to be a 235/35/18 though. That is a fantastic size that no one makes. That said, you can get a Michelin Pilot Super Sport in 235/40. That's what I would recommend you run. Tire and size wise.
