just to add to and old bumped thread.
IMHO the BMW oem pads have a great initial bite.
my Stop Tech Street sport pads don't have the initial bite that the oem pads did. not saying they aren't good, just giving feedback between the two's initial bite characteristics.
they do however dust less.
the oem pads are known to dust a bit. this from what i read years ago in an article is because the BMW pads use some graphite in the compound. the grapthite is what clings to the wheels and is dark. but the good thing is it doesn't embed itself into the wheels like more metallic pad material can do.
