I'm pretty happy with my 400/400. Natural balance is very mild understeer with 30lbs in all 4 tires. With the front shocks turned 1/2 turn from soft and the rears on full hard and tire pressure around 40f/30r natural balance is perfectly neutral/very mild oversteer, but easy to provoke into heavier oversteer by tossing the car around, braking or letting off the throttle fast.
