How long do Rotors last you?

I am curious to see how long a set lasts everyone. Just list if they are OE or aftermarket.
I did EBC slotted about two years ago and only put about 8K on them and pretty sure they are warped. Now, I did run the 1/4 mile a few dozen times this year so I was stopping pretty fast but I would think I should get another year or two out of them.
How about you guys?

That's a lot. You obviously drive almost HWY miles exclusively.

I'd say pads will last about 70,000 miles on average with a combination of city/ hwy driving leaning on hwy driving being the higher % of the two.

As far as the rotors are concerned, I'd say maybe 130,000 miles perhaps.

Idk. I don't like using rotors more than once cycle personally.

70/30 highway/city. But I do a lot of 100+ to 50mph stops, at least once a day. I have no idea why they are still going strong. The rotors looks like they need replacing, but plenty of life on the pads still.

Just developed a front end vibration at 87k miles. Front Pads look to be 70-80% worn. Just won some F series Brembos on eBay and will order new 340mm rotors and pads this week.

I bought a pristine 335i with 74000 miles. The rotors were pretty worn but still had decent braking and no pedal pulsation.
This car was one owner and driven carefully. You can tell.

Warped rotors has to be one of the most incorrectly diagnosed problem in all of automotive history. I would try to re-bed your pads and report back (read up on uneven pad deposits). You could also have worn suspension bushings that create vibration while under load (ie when braking).

I replaced my stockers at 75k, they were pretty much done. I installed Brembo OEM replacements and Bosch pads and I just checked them last week and they still look new at 108k.

Also, the "warped rotors" blame is mostly a myth. It's improper lateral runout that usually causes issues not "warped rotors". Gotta check the runout.
