2 piece rotor, center hat ?
What is the typical life span of the center hats on a 2 piece system?
thanks for your input, in advance

Depends on the use, loads, and also the mounting system.
Some will use a stand like the ALMS car above, StopTech uses a bobbin drive, Brembo uses a modified stand/bobbin, and PFC uses a split plate design.
The stands like you see above held up very well for side loads but the steel stands beat up the alum. hats pretty good on acceleration and deceleration so you had to watch that. The bobbin design like StopTech's would start to oval out the holes in the hats and you started to get a lot of axial load as well as increased float in the rotor.
Main thing is keep notes of what you are doing and how they wear. Each one is going to be different as it is going to be different for each car. I would say check it after 2-3 rotor changes and keep an eye on it as you change rotors from there on out.

I am assuming to get my remaining 5 w/e events this year out of the original rings as they are wearing great.
I will most likely hold off on ordering new hats until next year.
Great info,
Thanks
