A minor update, I found another set of wheels, here is a pic where I'm test fitting it to make sure it has clearance over the Wilwoods and won't rub anything.
Bought them used from someone off Kijiji. They came on his JDM Subaru Legacy when he bought it but he sold them because they were rubbing on his fenders. There are some marks on the tires where you can see it was rubbing but nothing I'm concerned about.
Regarding the wheels themselves, they are unnamed and didn't have any center caps for them so no idea what they are. I can tell you they are 17x7 with 5x100 bolt pattern but that is about all. The offset mentions 4/8.. no idea what that is but considering how they sit on the car, I expect they are about a +48 offset. They have some minor curbing marks and a few scratches but at least they clear my calipers with enough room that I'm not worried at all. I measured the center openings with a tape measure and it looks like it will take a 63mm cap and a 73mm ring. I've got rings here that I can test fit to be sure but no idea what I'll do about the caps. I think I might stop by the Subaru dealership and see if they have any caps that will fit on these.
The tires are cheap all seasons sized 215/45r17. All of them have 2015 build dates and have lots of tread left but one of them has a puncture causing a slow leak. Thankfully, the guy I bought them from has a spare tire so that will be simple enough to fix but he didn't have it with him to give to me, hopefully I can get it from him next week. Even if he doesn't come through with the spare, it shouldn't be much of a problem to get fixed.
For what it's worth, I noticed that this set of 17x7s with 215/45r17 all season rubber weighs noticeably more than my 17x8s with 225/45r17 winter tires on them. I'll daily this setup in the summer until I've worn down the rubber and then I'll convert them to a winter setup.
