Hi, just to elaberate, you want a drag tune for your GT-R 07.
Well.. the GT-R is probably not the best suited for the indy BUT, a fully modded GT-R will do best on open tracks if you take into account that downforce,camber, ride hieght,tires and trans tuning is the key. Asuming your GT-R is fully modded, setting your downforce low approx "10" your front camber to -2.0 and your rear to 0, your ride hieght to -15 with your spring rate to about 16.5 at the front and rear to 11 ...
This will really make the car handle allot worse BUT, you will find your top speed allot faster to achieve, as for cornering, the lower downforce at the rear will improve the cars tendency to understeer at high speed. As for trans if you stretch it right out you will sacrifice top end torque, so set it to 250 but pull your final gear back to 3600. And put racing soft tires on "WHATEVER YOU DO" GOOD LUCK PAL, LET ME KNOW HOW YOU GO.
