^^ It is! Not perfect, but good fun
Had fun at VIR last week with Trackdaze. I wasn't going for broke, but still obliterated my XP12/XP10 pads

Never had AWD off or oil temp issues. I hit maybe 280 degree oil temps... but it was only 65-80 degrees and I have to stress that I wasn't going balls out.
Here was VIR full with a 2:23.184 (with traffic):

and VIR Grand (Lighting Lap configuration, I ran a 3:09.9 if you start the lap at the old start/finish as I never got a single clean flying lap all the way to the new S/F location...):
