Not even close. 9-3 is 5x110 and the Saab 97 and earlier soccer balls are 5x170. I checked a while ago because I wanted a set as autocross wheels for my Porsche 356(with drums) and for some reason I thought they might be close.
In your case adapters probably cannot be made, as they would extend well past the hubs and might interfere with the brake calipers. They might be useable in my application though(I've seen wide-5 to 5x112 adapters, so why not?).
