There are a few threads out there with people attempting to use these calipers on DSMs. So far I haven't seem anyone pull it off completely or at least update their threads if they did. Yes, the bolt spacing is the same but offset seems to be way off and when offset is corrected, the rotors seem to be an issue.
Hopefully you can get passed this and figure out an easy way to make it work. I've wanted to pay with these myself for a while now but have yet to try. Good luck and post your findings!
