I've been looking and haven't found much. Is there a post somewhere that lists all the OE springs (C4, D7, etc.) and which cars they come on?

I'm in the market for a set of ZSP springs/shocks for an e90 328i and can't seem to make sense of which springs I'm actually looking for. The for sale listings seem to just state "ZSP whatever D5/D7".

It's out there....you just have to look for it:

Unfortunately it's not all in one thread...feel free to make one though in order to help out the community

Anyway, figure out what springs are on your current setup (C*whatever*) then just look for the D versions that match up with it: C5 -> D5, etc.

Thanks for the link!

I just went out and checked, our car has C5 front and C3 rear springs. So that means the sport spring for our application would be D5 front and D3 rear. Thanks!
