Spring rates?

[euroshark]

Anyone happen to know the rates of the stock US M3 springs? How about the H&R sport springs for a 6 cyl. E30?

Thanks

Stock M3 -> 140 -> 250
Dinan Sport -> 172 -> 300
H&R Race -> 315 -> 570
H&R Sport -> 185 -> 380
Eibach Pro-kit -> 102 -> 277
Eibach Race -> 160 -> 445
Ireland Stage 3 -> 315 -> 570
Tokico Kit - > 165 - > 265
Landshark Coil over - > 350 - > 450
Cosmo Coil Over - > 275 - > 375
Hope these are right. If not, please correct.
