Just to show you what tires can do for a lap time. During C&D Lightning Lap. C&D ran the RS3 with standard Pirelli Pzero PZ4 and the optional Pirelli Trofeo R.

Around VIR the RS3 with Trofeo R did a 2:52.5, more than 13 seconds quicker than the on PZ4s(3:01.9).
Trofeo R is more like a Cup 2 R equivalent - it is in a different solar system vs PZ4. (see my comment above - I may be wrong, but I think * PS4S vs * Cup 2 is much closer)
