Brake pads/rotors. How long are they lasting?

I know the system saids they should last about 25K miles, but what are you guys seeing real world?

I ask because I had my 15K service today and was surprised I didn't need new pads and rotors.

On my 335i, I went thru them every 12K on average, and since the M3 brakes are better then the 335i brakes, how do they get the additional usage out of the M3, yet still have better breaking performance over the 335i?

Are stock brake pads ceramic? I seem to get A LOT of brake dust from them when braking the same way I do in all my vehicles.. Don't want to replace them just yet since I recently picked up my car but it may be worth it. I expect to get at least 25k miles out of the pads with maybe resurfacing the rotors a little sooner.

BMWs have always produced an inordinate amount of dust for some reason. And also the rotors usually get eaten up with one set of pads, which is ridiculous too. Plus the fact a soft (dusty) pad shouldn't eat a rotor . Anyway, remember reading M3 rotors seem to be a bit beefier than on other cars, and don't need replacing the first pad change. But pads seem to be soft as always, due to the tons of brake dust. Hope to get at least 20K with mild driving. Curious to hear other owners as miles pile up on these cars. Good day.

Good to hear, since I plan on having my M past the warranty period

The answer is is many orders of magnitude in size. Spend time on a high speed and hard on the brakes track driving like a real pro and your pads will be toast in a few sessions. Cruize on the freeway and baby her and they will last 3 years.

Sorry, I should have clarified. No track/autocross. Mix city/highway driving with a few mountain twisties thrown in every now and then.

Sounds loosely like my driving. But I have done 1 track event (2 days) and 1 autocross (way less than I would have hoped due to being generally swamped). I have had my car for 1.5 years, have about 27k miles and the brakes are fine. I have not even bothered to check the wear levels.
