+1 on the 18s, there are no tires for 15s, 16s, and limitted for 17s.
You need to stay as close to 25" tall as you can. A 315/30-17 would be perfect but they don't exist.

Porsche is full of $hit with their comment on tall wheels. What's the diference between running a 25.5" tall 18 wheel with 12" wide tires or a 24.5" tall 15" wheel with 13.5" wide tires? I've done both on my SC for a decade with zero issues. Maintain your car properly and you'll be fine.
