OK guys think I may have posted about this in wrong place before but please forgive me as I'm new to this my question before was about ids springs as my front ns has broken at the bottom of the spring

I've been told it's only the shocks that are different and have been looking at getting the Eibach Pro springs but not sure if my budget will stretch to them.

If I decided to go with a pair of run of the mill after market springs does anyone know which ones are fitted on Signums with ids ?

Are they only for ids, lowered (Signum Design ) springs or standard springs
