I have eibachs on a car at the mo, and have used them before on cars.
I have always found them to be uttter shite until the last set I fitted, to a astra(Iwent in a astra with these ones), but if they are just std type replacement ones will be fine, the ones on the astra are basically GSI 16V ones, but very nice, with bilstein dampers, very good.
Eibach now make thier own springs as they did not before a few years back.
