Anyone tell me the thickness of the brake discs when they are new and when they need replacing?

sorry, found this on Renntech:

Brake disc thickness, new -- front 34 mm, rear 28 mm
Minimum brake disc thickness after machining* -- front 32.6 mm, rear 26.6 mm (* The brake disc must only be reworked symmetrically, i.e. from both sides evenly.)
Brake disc wear limit -- front 32.0 mm, rear 26.0 mm
Peak-to-valley surface roughness of the brake disc after machining, max. -- 0.006 mm
Thickness tolerance of the brake discs, max. -- 0.02 mm
Lateral runout of the brake disc, max. -- 0.03 mm
Lateral runout of the wheel hub, max. -- 0.03 mm
Lateral runout of the brake disc when installed, max. -- 0.06 mm
