Swap the tyres for slicks, the gearbox for the second to the left and lower the suspension to about half way. In theory you should have to make the suspension harder (it's a tarmac stage) but that doesn't seem to work so make it as soft as it will go.
The first chicane you come to, go straight between the two trees on the left. Just before the telegraph poles go over the hill and jump the chicane. The hay bale chicane is a bit of a dodgy one. Aim the car through the middle and floor it - nine times out of ten you should make it but occasionally the collision detection will go a bit wrong. Other then that minor glitch and this stage can be found as the Rally Championship demo on the official site (see the links page).
