N12 Lowered Heavier! Springs??

[Daz]

Hey,, Has anybody found a good spring setup for an N12 as I have heavy duty lowered K-Mac springs but are just standard rate when inspected, just a lower height, making them supossedly heavy duty.. I would rather a thicker coil and about a 40% increase on standard.. I have only found a place in N.Z that will make a specific apllication for me.. Anyone found a local company???
Also what are the best front strut/shocks ?
Thanks
DAz.

industrial springs here in adelaide will make springs to your rate and height

king springs, jumboz, the list is as long as my....... well lets just say its long!

coil thickness has absolutely nothing to do with spring rate. It all has to do with the heat treatment of the spring and the composition of the metal.

a good example is this, compare the spring of a coilover to a stock spring, the coilover is tiny, yet it is also alot stiffer.
