Whats the set up for tuning a ford gt40 for forza 2

the 1966 ford gt40 in forza motorsport 2 is really only good for the Nissan speedway and you should first buy all the upgrades. (All of them the most expensive or furthest to the right.) Then increase ur tire pressure to about 35psi. (front and back). the main thing for this car is that you take out the 4th 5th and 6th gears on the gear ratios. then set the final drive to the very edge of the graph on the side.leave the springs and damping alone unless you want to tweak your handling a bit. (you'll have to play around with it). Then change the antiroll (antisway) bars all the way up and the differential all ther way up too.
Your welcome and hope this answered your question.
