Rhys, I don't have seen any lap of you. But to give an advice beforehand: Do not overdrive the car! The track might look easy and small mistakes seem to be not too affective. But they are, more than the average on other tracks. Driving slower is faster here. For example, if you are just a bit off the line in the two right handers after the second back straight, especially the second one, nearly a whole second is gone (if you miss both)! Also the twisty section in sector one is very important. There exists exactly one fast line (which I am also do not hold all the time). The only part where you can take different lines with the same result is sector three, but also it is extremely important to get the last corner right, otherwise you throw away the whole lap.
For me, it seems that this track is 100% a driver's track. The setup has only a very small relevance. I tried several approaches with the setup, all with less than a second difference. It was just a matter of adapting the driving style.
