I have not noticed this issue yet but I noticed that the piston dust boot has been heat damaged to the point that I can see the damage. I wonder if extreme heat like that is contributing to or causing your guide pin issue. I'll run the stockers til either they fail or I save up enough to swing a BBK. I really wish BMW didn't put floating single piston calipers on the M3 though...
