lowering spring specs for Yaris

[botchilah]

Since I originally posted asking about different lowering spring rates for the Yaris NCP91 chassis code, I started searching around until I realized I have a Hyper Rev magazine for the Yaris (duh!)

So I copied the rates and drops and am putting them here. MODS I hope you make this a sticky because this would be most helpful for everyone!

* The specs for the Tanabe NF210, DF210 and Progress Springs I took from the Microimage website. The rest I took from my Hyper Rev magazine.
** I used 56 to convert kg/m to lbs/in vis-a-vis.
*** Hyper Rev lists a range of the actual DROP so I simply put in the lowest drop but the variance is only 5mm from highest possible to lowest possible drop of the springs.
**** All spring rates and drops in inches are rounded off to the nearest 100th decimal for simplicity's sake. At most you're looking at 0.02 variance.
***** If there are any errors please do post up and tell me so we can correct it. Thanks!

If anyone wants the drops and spring rates for popular lowering springs for the older Yaris / Vios platforms and chassis, PM me your chassis code and I will post it here as well. Right now these are for all NCP91 chassis Yaris.
