for transmission i just adjusted top speed.
you have to be careful with throttle, as with most drifters, but is an easy, controllable car to slide in the tighter tracks I.E. Eiger Norwand.
EDIT: having bought the 180sx and the 240sx and the other silvia's i find this tune is very suitable for those aswell maybe just slightly tweaking the spring rate depending on the weight of the car
