From the last patchThey're on the newest tyre model now, same as most of the other cars. Other than that, the only change since the GTR 4 Series is the new Audi.
Well, they do come up in rotation but with so many great classes available in this sim, the cycle tends to be quite long. That said, I plan on running a second series for this class in June. So that'll be four weeks in a row of GTR 4 goodness.Ross I hope we will do more of this GT4 stuff in the future I think this is my new favourite car category in Raceroom
