CM Min rotor spec question
Is the minimum rotor thickness (24.5 mm on my c5z rears) a spec for taking them OUT of service or a spec for putting them IN service?

I had my dealer turn some oem rotors and they came out great and/but they are exactly AT min spec give/take .001 mm.


So are these good or junk?

He seemed to think the min was good to go INTO service.

Thanks!

BTW I would not track these, street/autox only.

HI there,
24.5 mm is the discard specification.
24.9 mm is the MINIMUM THICKNESS AFTER MACHINING per SI document 912299
Discard the rotors, DO NOT USE THEM.
Allthebest, c4c5

I use old rotors to hold down my easy-up awning
