I haven't had to replace mine yet but I would get them from Audi. Don't really know of any suitable replacements but haven't looked hard enough yet. As said, the proper way is to weigh them.

As standard, every new refurbished disc will get new nuts and bolts.

the process is something like this

- Discs are weighed and depending on wear and wear pattern and rotors are x-rayed and examined for structural damage.
- Brake pad residue or contaminates is chemically steamed off
- Discs are machined until they are level
- Napped are vacuum soaked in polymeric carbon
- Pyrolyze the discs at 1100°C
- The last two steps are repeated three times
- Discs are siliconized at 1500°C
- Top layer (ca. 1mm thick) is now restored, and trough the pyrolysis it is chemically and physically bonded with the structure
- Final sanding of top layer
- Disc is reassembled and weighed once more and precision-balanced
- The disc now has gained about 30-50g and is at desired value once more
Do you know of any UK company that does this?
