Eibach Rear Springs - Technical Data Needed

[phoenixcsl]

I need some help...

Does anyone have a set of Eibach lowering springs to hand?

I would like to know the following:

1/ Spring Rate
2/ Internal / External Diameter of top coil
3/ Internal / External Diameter of Bottom Coil
4/ Spring Length

I want to see if they are shorter / same rate as my Nitron / Eibachs, as my rear ride height is too high still and i'm out of adjustment.
