hey there...
was reading your thread, but im from Australia...do you have "king springs" over there???
because if you do, look at them, they are very good, and you can get them in a variety of lowered settings...
if you want bout up to 2inches lower look at the 'super lows' series.
...if you want up to 3 inches look at 'ultra lows'
when i say "up to" its because depending on weight, and the spring (they are not cut identical, and at a perfect length)
also, if your planning on going shorter, i would consider getting shorter shocks aswell, for the simple fact that because the spring is shorter, it throw on the shock will be to long for it, and if you hit a bump and get some air, your spring could fall out (it has happened to a friend) hahaha
but if they arent over there...i wouldnt know if they would be worth shipping over there
hope that was a bit of help
