Well everyone thinks you need to reef on the set screw to tighten it. I pretty much just hand tighten it. Where's it gonna go after all. With the e46 rotors on my car right now they don't fit at all, as they moved them so that they don't line up with the studs, and it is a bit of a pain to make sure the studs are lined up if they move.
It's either the stoptech kit or performance friction, can't remember which now.
