I was a little concerned the eibach pros might decrease my ride handling and give me a softer ride.
I know when my rear spring was changed it was with a OE sports spring.
Why should the Pros be any softer?
They'are slightly stiffer in fact.
I'd go für Eibach Pro or Volkswagen OE springs and if you can afford it,
add some good dampers like Bilstein or at least OEM GTI.
