Maybe Hacker or casper can let us know how they shim there's. I'm going to guess it's by the book.
The 1.0 I have has never had to be re shimmed since it was new and I have let my 5yr old drive it pretty hard some days while learning track etiquette. Original r/p still on it and it spins very free now.
I just finished the front on the 2.0 and I thought it was strange that there was not a shim used in the front too.
