Stock Rotors Average Lifespan
I'm at 42k miles and stock pads are getting pretty low, so I'm planning to replace them in the near future. Trying to figure out if I should go ahead and replace rotors also, or if that is complete overkill at this point.
My rotors have a noticeable lip around the edge, but I don't have anything to measure the thickness accurately. There are no cracks whatsoever and no vibrations. I know there are a million factors that can influence how they wear, but is there a general consensus on about how many miles the stock (steel) rotors should last under normal street driving? |

No. You need to measure them to assess how much life is left. Good luck.

Just do the pads, they are a really easy DIY.
Now, if your rotors look like mine on the 2019 M4, it’s rotor time. As a reference: total miles 22k & track miles 3.5k, I have been beating on this beach.

Yep, probably just going to have to get a micrometer then, but haven't needed one for anything before this. No sign of any fault lines yet
