Springs at min in front and max at rear. Ride height to 55 front and rear. Camber doesn't matter, but make sure you have both frt and rear toe angles at zero. Minimize downforce at both ends. With default tranny settings, change the final to 2.920 or so. This should give you 260+mph with 984 hp. If you're running without the turbo upgrade at 724 hp, simply move the final ratio up a little to comp for the lower power. Hope this helps.
