Firstly, which version are you using? '03 (Tantra) has more useable track
(beyond the kerbs) on Castrol and Gosser Kurves.
Castrol: 2nd gear, turn in early just missing the barrier with the car high
on the inside kerb, run out as wide as you can get away with, with maximum
throttle.
Remus: 1st gear, brake *very* late. You can brake as late as the 50m boards
because its uphill (the same is true of Castrol). I tend not to go past the
outer kerb because I find it slower.
Gosser: trail-braking, well past the 100m boards, balance the car on the
throttle as you approach the inside kerb and let it drift to the outer kerb.
I don't like to touch the inside kerb as it pushes me wide.
Lauda: 3rd gear, accelerate to 5th as you hit the outer kerb.
Berger: 4th gear, IMO the hardest corner to get right. I find it best to
turn in late and not touch the inside kerb, it always pushes me wide and I
have to lift to stay on the track. Exiting, I ride it right up onto the exit
kerb.
Rindt: 5th gear, use a little kerb and run very wide (to 6th gear) just
before A1.
A1: same as Castrol. I get very close to the barrier and have taken myself
out of races a few times :o
