This happened on mine and I went the eibach sportline route.Front driver side spring had just decided to snap on me!! Been thinking of lowering it so this has made my mind up for me.
So instead of OE springs was wondering what ones would be ok to use with standard dampers?
I think it depends what you want. I have the Eibach pro kit springs and KYB dampers and the car handles and rides very well. The Sportline spings are going to make the car handle even better, but you will have to sacrifice more ride quality, and on todays roads that could be a real issue. Also a bigger drop is likely to make the standard dampers struggle.
I had Eibachs, now have cooksports and prefer them, more of a drop and better handling IMO
