Hi there, well here is a complete parts list of the suspension components that I had refreshed just this past January.
Along with these, I added H&R stage II springs for the 750 and bilstein shocks on all four corners. Best thing is to delete the EDC/SLS system as they tend leak/break eventually and cost some serious coin to fix, so you are better off deleting the system and going with conventional springs and shocks.
A great resource for our cars is www.E38.org
with tons of tips and tricks for known problems.
If you are not mechanically inclined, then I would hightly recommend Charlie @ Bimmersport Automotive as he quite familiar with my car and has done all the work for me.
