0 is perfectly fine for drifting. soft springs in rear and medium up front is what i run. throttle response may be fast, but if you learn to pulse, then your drifts will get better, as xmods work mainly with the pulse-method of throttle control rather than smooth throttle (xmods have too few throttle steps for the smooth method)
practice a lot. it's the best thing to do for drifting.
