Looks like they will be about 1.75in or so inside the fender. Not too bad. Right now I am more concerned about the inside and it looks like it will be ok there. Will be getting something that fits better eventually, I just need to get it on the road so I can drive it and see what else needs to be replaced xD
Pay particular to the inside edges of the rims and tires. There's a very good chance that they will interfere with the rear strut or knuckle. If they are factory Subaru wheels, you will also have to enlarge the center hole by 1 mm. The Scooby uses a 56.1 mm centerbore, while the Fiero's is 57.1 mm.

This would be my biggest concern. I don't know if they will clear the knuckle. In this picture, the pink represents the wheel. The stock 15" wheel is almost right against the knuckle. You may actually be hitting the knuckle with your wheels.
