@ 90K miles on my 2013 CX-5 and need to replace the brakes/rotors

[Surfsup]

Good to hear you have 90+K on brakes, I have 45,000 on mine with no issues.

Note, a highway driver with 90k miles might have less brake wear than a city driver with 30k miles.

The softer the pad the more wear on the pad and the less on the rotor so I can usually replace the pads a couple of times without even turning the rotors.

Exactly, decide what you want but most people would want softer pads producing less wear on rotors. Though rotors are usually $20 a pair these days - they are meant to be replaced. (at least they were $20/pair for my previous Isuzu which was great)

Instead of turning rotors I usually just replace them as turning reduces the thickness of the rotor and they will heat up faster and be more prone to crack. I can easily switch rotors and I have to get someone like NAPA to turn them and it takes more time and does not save a lot. I used organic pads from Autozone on a G35 that is famous for using pads fast but had good luck with them

Not sure where you live GAXIBM but most reputable shops will not turn rotors without a minimum thickness. Since most product today (I'd say all but I don't know 100%) is made to be cheaper and lighter, the rotors supplied are likely universally un-turnable like the old days. The moment there is a groove, the rotor should be replaced. However, I've been known to just put cheap pads on a grooved rotor to go one more brake change. On my Isuzu I needed brakes every 20k miles, so 90k is amazing!

No, you can't buy rotors that meet spec (even for an Isuzu) for $20/pair. Not all rotors are created equal.

New OEM Brembo rotors for the front wheel of my Ducati are $300. I've worn out three sets in 60,000 miles.

You might try Med Center Mazda. I've ordered from them before and had good luck.

Is it really necessary to replace the rotors if they are not damaged? I've never had to replace a rotor on any car I have owned, only had them resurfaced.

If they are under material thickness minimum specs, yes.

I would throw warped rotors into the category of "damaged".

Check the cost of rotors vs turning, I prefer to pay a little more and replace.
