Its in the Exclusive Series (17.1). I haven't tried it personally but it is generally been said to be harder than the FXX-K/McLaren but still fairly doable. It doesn't pay quite as well either(500/lap base vs 600/lap) and obviously lap times are longer. The R8 LMS has the same race/fame as the 918 RSR in its ES (16.1) but is said to be more difficult to do as the car is slower.

PTT Short is in other series as well, but tends to be 300/lap base making it not worthwhile.
