Hello there
I have a 1990 316i which I'm looking to engine swap to for a m42 soon. I also have a donor 325 which I'll be taking the 51mm struts off for some extra strength.
Now I'm looking to get new Bilstein B6 shocks and H&R sport springs and am having trouble working out which part number is the right one.
Are there different shocks/springs for different strut sizes or are they the same? Anything else to note when doing this?
Bit of a novice when it comes to this so any help would be much appreciated
Cheers
