I've searched a lot (NASIOC, here, web, etc.) and haven't found much.
Some spring rates I've found, for comparison:
Spring Rates (pounds per inch)
------------98/01 2.5RS---Liberty B4---04 USDM STI---V6 STI "Gymkhana"
Front------157-------------143-----------224-------------286
Rear-------149-------------271-----------194-------------274

Why is it so hard to find stock spring rates for the 00-04 BE sedan? I found a thread where someone tries to interpolate the rates: viewtopic.php?t=3748 (http://www.sl-i.net/FORUM/viewtopic.php?t=3748). Anyone know?
*Edited out a dumb question here about why the rear rate is so much higher than the front (answered below)
Are spring rates the same across all B4 variants? (I'm pretty sure they are)
The B4 front spring rates seem conservative; they're lower than the 2.5RS, even though the B4 is heavier. I didn't expect that?
I'm in the middle of installing my used B4 suspension, and I think I'll be pretty happy with it, but I want to make sure I'm thinking this through so I don't end up ripping my suspension apart again in a few months because I want different springs.
