Turn the traction control completely off. I turned the dampers and the springs up a bit, put the ride height at 0.
First couple of corners are really important. Go round the outside of them and try to get infront of that annoying yellow car. If you're not in 3rd by the time you get to that tight S bend turn in sharpe and go across the grass. You'll get a 4 sec penalty but its quicker! Hope that helps
Just so you know you need to do all S class b4 you can buy the F1 car. Don't just need 2,000,000!
