BMW Performance Suspension research

I've gotten a few emails regarding upgrading to the BMW Performance Suspension. I did a lot of research to find out what parts I needed, what goes where and the little details that I needed to do a complete suspension refresh. Keep in mind that I'm coming from a non-sport setup so I did everything down to the bolts and washers. To avoid writing the same thing over and over again through emails and PM's, I thought I would post my research here.

Peformance Suspension Part number: 33 50 0 429 577
Complete parts list of the package:


Front axle diagram and parts list:

Rear axle diagram and parts list:

Cross reference all 3 sites then you'll be able to figure out what else you're going to need to buy. Since there are so many little items, I put everything into a spreadsheet. It was the only way I could organize.

The following parts list may be incomplete because I ordered a few odds and ends seperate to the list. I did upgrade a couple of parts which include M3 RTABS and M3 RSMs.
