rxsumo 33 Report post Posted January 9, 2009 Hi Does anybody have access to the factory CD or "blue book" service manual for the 2nd generation E12. I'm looking for the front and rear spring spec's for the M535i. I'm interested in the details listed in the service manual, as this listing actually has the real information as opposed to the parts manuals that only have the 11 digit part number. I'm looking for this sort of info....stolen off the First Fives forum, but only covers the US models: P/N: 1 112 867 (530i through 1976) relaxed length: 352 (13.858) relaxed pitch: 78.61 ( 3.095) wire gage: 13.5 ( 0.531) diameter: 164.5 ( 6.476) total windings: 5 active windings: 4 colors: blue stripes along entire length of springs plus red, white, or green stripes depending on spring rate. red: 3649 - 3738 N / 372 - 381 kp / 820 - 840 lbs. white: 3747 - 3845 N / 382 - 392 kp / 842 - 864 lbs. green: 3855 - 3955 N / 393 - 402 kp / 866 - 886 lbs. The suspension on my SA M535i has been "monkeyed with" (I'm just replaced the rear Koni's and cut springs,with my Bilsteins and some unknown BMW stock springs), and I'm trying to return it back to a more "original" motorsport spec.
