transfers torque split as fas as i can press/release the button. yeah it’s not 100% RWD, but sends some 80% of the torque to the rear wheels making it act like a RWD car. only on 04/05 gearboxes and early 06’s can do it, after that they switched center diffs and the torque split can’t be as great to the rear. Car drives like a skyline in that mode(AWD with RWD torque bias). REALLY helps in getting the car spun around on a tight hairpin.
I never even touch the hydro ebrake anymore to rotate the car.
