Eibach competition springs

I thought I had found a bit of a bargain last week, bought a set of eibach springs second hand but almost new, advertised as eibach competition springs for fabia vrs.

I asked the seller for the stamping from front and back springs, checked them on the eibach website and the front and rear stamping matched up to the 25 mm lowering springs, however.. I have since found out that the competition springs are a lot cheaper than normal eibach springs.

Are these of no use to me for lowering purposes?

Thanks for any advice
