I don't have the correct data but maybe Colin (HH6) knows it. Or try to call Ralliart.
On my new movit disc it was only 0.01mm. As I've already said if they've already became too hot check the run-out of the hubs and bearings! The OEM bearings are quite shitty, my new ones already had 0.05mm play when we fitted the new brake kit. If the bearing has too much play it will destroy every new disc in 1-2000km regardless of the quality of the disc.
As your car is certainly still under warranty try to replace all the bits on their cost. That's what I did before I fitted a real brake kit, not the standard ****.
