With minimum rotor thickness going to 12.2mm from 13.25mm, is there any reasonable basis for a future reversion to 13.25mm?

SCCA _e sent a letter explaining the delay of Wilwood rotors. Enterprises is allowing the older solid rotor. Also the minimum rotor thickness od the vented Wilwood rotor has been reduced down to .481 from .522. I can not finds the letter again..... So it is important to understand and the length of these changes.
Call your CSR ( I may be wrong... it can happen LOL)

I would say "no." Of course I don't know what the original basis for 13.25 was.

Being a cheap guy generally, this is a fairly big deal on an expensive consumable.
New rotors are about 15.7mm, 13.25 minimum means 2.45mm usable life. A minimum of 12.2mm means 3.50mm usable life which is 40% more assuming linear wear.
