Should I buy these springs???

A guy in BG is selling a WEITEC springs in very good price(he bought them and didn't like the comforf of driving)

Tuning.BG • ??? ?????? - WEITEC ??????? ?? Skoda/VW/Audi... --????--

I want to ask?

Did they work properly with the standart suspension,or not?

What is the diference between them and Eibach ones?

Is Weitec more hard?I think for the lcar like Fabia the best way is hard suspension,and soft springs-Am I right,or not?Please tell me???:confused:

With other word-should I bye them-because my Fabia is with the stock suspension?

And I want to drive it every day?

Any opinions?

Thanks in advance!

(the car is Fabia RS )

Best regards,

Iskren
