The car came with 4 of the Dunlop's on but two were bad so I replaced all of them with Continental Sport Contact 7's.
The SC's are of course excellent, if not a bit noisy. They wore out and I made the decision to get 2 new Dunlop's and put them on with the older ones that were only about 5% worn.
So this is a direct comparison of the two tyres back to back.
Objectively over a variety of driving styles - motorway, town and fast country wet and dry and some snow (I have winter tyres) the only difference I can detect is that the Dunlop's are quite a bit quieter.
My only concern is that the Audi being what it is could make any mid-range tyre and above look great!
