Got a set of these on the front of mine. Very happy with them - had a set of them previously fitted on my old mkiv, which replaced a set of Dunlop Sport Maxes - no problems with wear really. Much quieter than the Dunlops, and the Toyo Proxes T1S's (fitted before the Dunlops).
With my mk5, I did a trackday when the Contisports were 2-3 weeks old - caused a bit of graining on the front edges, but since then, they seem to be lasting very well (6-7k covered).
Feel good (much better than the Linglongs the car came with) - grip well, quiet, cost is ok. I'm happy with them.
