I spent about a half an hour talking with the parts guy at one of the BMW shops here in town hoping that I could get an idea of the cost to retro my non-SP car with the springs and shocks/struts of the cars with SP. He was very cool and didn't seem to mind the extra work but we had to come up with a VIN off an SP-equipped car. Simple enough, went out to the lot and found a used one. I had to leave and told him I would call back to get the specifics. When I talked to him, he said he talked to one of the master techs who frowned upon a retrofit because there were "way too many possibilities" for the setup. He offered to get me a Dinan suspension setup instead that, he said, would only lower the car by .75".

Two questions:

1) Should I just give up on trying to retro the SP springs? In theory, it doesn't sound too difficult - buy the springs, get a set of Koni FSDs and get them installed. That's basically what happens when you buy an Eibach kit, right?

2) I'm not familiar with a Dinan kit that lowers .75" My initial response was that was for cars already equipped with SP but I didn't want to argue with the guy over the phone when he hadn't even quoted me pricing yet.

Any thoughts?
