Well to be fair, and I dont know if it also includes the RS3, but you can spec the dunlop sportmaxx race tyres from the factory now, and they are on par with the supersports if not racier.
I recall a mag questioning a audi boss about why audi's are like this and his response was that an audi has to drive like an audi even the RS models as thats what apparently customers want. And having spent some time on the TT forums and reading some of the stuff the guys over there want from their cars I can see why. Sad for us, but at the same time I suppose thats why the VAG tuning scene thrives so much.
Im surprised at how good the BMW sounds, very nice, sounded like a NA car imo
