The BS matters too....the OEM's seem to fit, the after market jobbers with less than 5.5" of BS seem to hit.
I've seen people grind off enough to clear the calipers on 15x7's...Dagger's got an SC, and he says the brakes are the same size as the non-sc....and clear STOCK 15x7's no problem.
Its possible that there wasn't enough BS on the one's you were looking at to clear the brakes.
You could try them on for size to see for sure, or go to 16's...or just keep the 17's the sc came with, etc.
I assume yo want the cheaper rubber prices for the 15's though...so get 15's with more BS, and clear the brakes, and call it a day.
