The trouble i have is my current space saver doesn't fit on the back or front. I'm hoping the 15" clears the wilwoods on the front. I've always done as you say as I've always had cars with LSD.
Think you might struggle. Even the 15s aren't that large, I also don't think caliper clearance will be great as the space savers are pretty flat and the wildwoods sit a little wider IIRC.
