Yeah, I think you should be good with that. I've ran 235 on an et42 wheel and that seemed to do just fine. Looking at my notes, the first time I ran 245 was on that same wheel with a 5mm spacer, so you should have a few mm to play with.

I've ran small spacers without issues, but YMMV of course. If you're just worried about length, the stock bolts will probably do just fine with these small spacers.
Studs just make life much easier when swapping wheels often. Just be aware that they are a consumable (I've had quite a few snap) and have to be replaced somewhat often if you track a lot.

Careful what you wish for, our cars are certainly capable of that with the right tire
