Stock OEM BH9 GT-B Spring Rates?

[gryffinwings]

Anyone know the spring rates on the JDM Bilstein suspension on the BH9 GT-B Legacy Wagon?

Not exactly the GTB model, but maybe it's close enough to what youre looking for.

Whoa!!! very nice! The Spring rates in the front should be the same but the rear would only be a little lower so that should work just fine.

Here's is the stuff from that article:

Front Suspension
Damping Rate - Bump/Rebound (N @ 0.3m/s) 932/2159
Suspension Travel - Bump/Rebound (mm) 105/95
Spring Rate (N/mm) 25.1
Swaybar Diameter (mm) 20

Rear Suspension
Damping Rate - Bump/Rebound (N @ 0.3m/s) 600/2350
Suspension Travel - Bump/Rebound (mm) 125/85
Spring Rate (N/mm) 47.5
Swaybar Diameter (mm) 17

Now according to this the:
Front Spring Rate: 25.1 N/mm
Rear Spring Rate: 47.5 N/mm

Does anybody now have the conversion from N/mm to lbs or K?

Ok, just to keep this all in one thread, B4 Legacies got 2.56kg/mm F / 4.84 kg/mm R.

Keep in mind the B4 uses a stiffer and slightly lowered suspension.
