Wheel Sizing & Watch Outs for a 1st timer

Currently building out my first Porsche 911 ever. Very new to this journey and wanting to soak in as much knowledge as possible and there are a ton of gaps to fill.

I've dug around this forum and have read a lot of posts but figured it would be the most helpful for me to ask my questions directly to you all.

I am building out a 1971 911 with my own touches to it. My rear flares are 1-1.5inches wider than SC flares and I'm worried the Fuchs I have, 15x7s, may be a bit too small. Wanted to pick the brains of the experts here and ask about the following:

1. Are 15x7 all around going to be okay with the flares that I have?
2. Should I explore going slightly bigger in the rear, say 8s or 9s?
3. If I do explore going bigger in the rear, how will that affect the handling of the car? What are some other things I need to put into consideration?
4. What kind of effect do spacers have?
5. If I explore a wider rear tire size, would that be an alternative route?
6. What am I not thinking about that I should consider?

Thank you all for your input!
