Many of the drivers are probably very familiar with the track from GPL, so
it shouldn't be too tough.
I've only ever done about a dozen laps there (GPL and TA cars combined), but
judging from the laps I did tonight in the TA car, I think it should be very
good for a TA race. The setup that comes with the track felt stable as well.
