Currently have a 1.40:700 in the Zonda and a 1.34:600 in the BMW. I did manage a 1.40:300 in the Zonda but it had a penalty. I now know how to get a 1.39 and shall attempt this tomorrow. Im using the controller by the way. Little tip for you in the Zonda. Take the right turn before the tunnel in 4th gear also the left hand turn after the tunnel you want to drop to 3rd but short shift to 4th as soon as you exit.
