The suspension setup is very nice. Excellent balance on the car. I drive without the Turbo, and with R1 tires (endurance race setup). With the transmission set to auto 10, this car does very well on Tokyo Route R246. After switching to this setup, I improved my lap time by 2.5 seconds on the first lap (practice mode), and that wasn't even trying very hard.
I also have the ASM/TCS set at 1-1-2 (standard enduro configuration for me). Saves on tires without any significant top-speed loss.
