Boy oh boy this was hard. Second hardest challenge I've ever encountered in Assetto Corsa, actually - after the GT's against Godzilla challenge.
Firstly, I had to soften the car up a LOT since it kept bouncing way too much for me. I ran both springs and antirollbars near their softest settings. Then it was the matter of adjusting to the car itself. Last time I drove this thing was in Need for Speed: Porsche Unleashed, which is 20 years old by now. I had some work to do. In all honesty though, after a few setup changes - it did not take too long to adapt, as it is quite nice to drive if you have a disciplined right foot.
Hardest challenge by far was the AI. They are not crazy quick, but they completely ignore the player and will move you aside by force if you're in their way. They pushed and shoved me so much that it took me an hour to complete this challenge. In fact you can see that both the leading cars tried nudging me off shortly after passing them - just because I was on "their" line! Lame.
