Excuse my ignorance but if indeed the discs are to be replaced with this fix, will the hubs be changed too, i.e. are they a unit or separate? I don't want to spend time and money cleaning/painting needlessly.
On another note, having driven a Q7 around for 24 hours, I am loving having the RS3 back - so much power, such a solid drive and now that the exhaust mount problem is fixed the myriad of little irritating squeaks/rattles have gone away. Happy days!
