I'm not actually using those discs they fit on the hub ok but the caliper is about 5mm to far back for them to fit i need to take of the adapter and place a spacer in between the adapter and the hub and all will be ok only trouble is the bolts are stuck fast and i have tried every thing but no joy. I have a8 discs on the car never had trouble with noise before and it starts as soon as you pull off and its quite loud

I have just checked the specs. Merc Spigot Diam = 67mm.
Audi Spigot Diam = 68mm .

So they may appear to fit, but will not be fully seated on the hub.
Bolt stud holes also vary from one Merc disc rotor to the next so they need to be checked verse the Audi specs.
Also check that the center bolt is torqued to correct spec.

Good luck.

I have already done the centre hole and the disc fits the hub fine, it's the hat height that's wrong.
