This set up gives pretty good oversteer, nice acceleration to 200 but watch out on the tight corners; This car doesn't seem to want to turn under hard braking. It still needs work there. I think after moving extra power to the rear, and loosening up the front end, this car could benefit from changing the TCS setting. Of course I also think that there are other ratios for the tranny that would work better, but this gave me a good acceleration for the tight sections of the string.
