225/45/17 is the easy button and fits 100% even with the stock +48 offset. I ran a 3mm spacer on mine, but it wasn't necessary... so I had an effective +45 offset.
Since I'm running a +45 wheel, I'll be able to fit 245's without the spacers, correct?

It depends where you are with autocross. Given you're running the RT660's, you're probably not up at the top. RE71RS are the top street tire now-adays. I had the RT660's and for an autocross tire, I kinda hated them. By about run 100, they were more or less dead in terms of heat cycles and grip, yet they had plenty of tread. I ran them out to 230 runs, but the last 100 runs were dreadful. Between RE-11A's, RE-71R's, Hankook RS3's's, and A052's, out of all of them, I wanted the RT660's off the car the most.
Interesting. I'm about mid-pack in pax overall, mid-pack overall in raw time, and usually in the top 1/3 in class. I'm not setting the world on fire, but have made significant personal improvement last season as I got more familiar with the car and started using a 220TW tire.

I usually run about 8~10 events a season so 50~60 runs a year plus the 45min drive to/from the event location. Since I was buying a full wheel/tire package I went with the 660's to keep the overall package costs down, and honestly have been pretty happy with them. When they need to be replaced I'll likely move upmarket to the Yoke's or Bridgestone's.
