When my saph was stage 3, I had a decent set of leda coilovers and sensible ride height with polybushes all around and it was a dream to drive. Took it on a few track days and the newer shape m3 couldnt keep up with me round brands hatch. Aslong as you have a good make of tyre all around, renewed bushes and suspension which isnt to low, in my opinion the car handles as well as it needs to at that power level, round bends and on the straights.
