After a grand total of 3 laps I have these splits:
22.205
37.253
Not great, but thats with the conservative lines i use when racing here. I'm sure with practice I can go much quicker. There is seconds to be had just by using all of the kerbs. It's fresher's week and have just settled in to my new flat but I may not have much time to practice this week.
I think I prefer the arcade combos, if my times are slow I know it's me and not the car, so I just practice rather than altering the setup. The DTM event at the Nurburgring and the Sauber last week show GT mode combos are a weakness of mine.
