Does anyone know what the geometry settings would be on my 03 sti if i went for the Prodrive spring up-grade.I have also seen Eibach springs for sale at TSL/Scoobyworld for £170 inc vat (is this a fair price) are these the same as Prodrive would use?

No they aren't the same as the Prodrive ones. You get the Geom settings when you buy the prodrive springs. Can't remember what they were off the top of my head.
