I wouldnt grind calipers myself, but Ive heard of a few doing it. No idea on safety of it, but I wouldnt think it would be that bad if your only taking a small bit off.
Really not worth doing to fit wheels that are too small though. If you'd got at least 17s you probably wouldnt have had a problem with calipers lol.
