Ahhh forgot about your evil driveway.. although I have not seen your driveway in person, you said last time that there was no possible way to go up on an angle? If not, I guess you have to go springs/shocks combo as it will be cheaper and more suited to Australian roads compared to imported coilovers. My driveway did not even let a stock Corolla or Yaris go up without going on an angle LOL.
Yeah, it's not that bad (for me anyway, I prefer better handling > heaps of comfort). You feel it especially over huge short dips or pot holes in the road or over diagonal railway tracks. But saying that, I can cope with it; some people who love comfort would not be able to.
