I called the company (MGP) for assistance but they wouldn't speak to me because I hadn't purchased from them. I've never written a review for anything in my life but this just pisses me off. Terrible company! They come with the wrong rear caliper clips. Don't buy from them. If I could I would give zero stars. Called Revain and they can't help. You will only bring them back. Now I have to remove them from the front so I can get them back. Pretty unsatisfied all round!
