does anyone know the standard thickness of new disks on a my00. and min thickness.
and the thickness on godspeed 335mmnew and minimum?
is there just 8mm difference?

Standard 294mm discs should be 24mm new and a minimum of 22mm when replaced.

yes standard disc new 24mm , minimum thickness 22mm , the Godspeed 335mm discs are 32mm new with a minimum thickness of 30mm , the grooves are 1mm thick on all Godspeed discs , so they also used as wear inicators , when they go the discs are worn out

thanks people , 8mm difference as i expected!
