Bryan,
I don't think we have the M-Sprt pack, or the ZHP in Aust. Could you elaborate as to what those packages offer and are they able to be retro fitted?
We can get performance handling upgrades, but in my opinion one is better off getting proven aftermarket equipment like H&R or Eibach etc...I did look at Gold Chipping the car but was talked out of it as really getting poor bang for your buck. Chipping here cost's $1300 where as I can make some nice suspension mods for less than that, and as we all know, dollar for dollar, better handling will outperform increased power, certainly of you ever hit the track for some fun.
