Spring Rates for GTS and ACR?

[Irid]

1999 GTS = ? F/R
1999 ACR (w/Koni shocks) = ? F/R
2000 ACR (w/Dynamic Suspension shocks)= 500/1100
Mumford's ACR (EMI Penske's) = 600F/850R

Help me fill in the blanks here...

My 2000 ACR had the Koni Setup (some did, a little fyi) and I believe the spring rates were the same as what you have listed for Mumford - 600/850.

I believe the spring rates on the 99 ACR were 400F/700R, or something very close to that.
