I have read a thread on the astra owners network forum about different springs for lowering an astra H sports hatch (http://www.astraownersnetwork.com/sh...lowering+astra), i have been debating on either the Eibach Pro Kit which is 30mm all round or the Eibach Sportline Kit which is 50mm Front and 30mm Back.

I think both would suit my car down to the ground but im unsure which to buy, has anyone tried either of these kits and could give me a brief overview? Thanks alot
