Late, but couldnt find it anywhere on here.
Just as an example, standard rear 323i ones are 701-703 lbs. However, the lbs figure is lbs/ft, not lbs/inch, so the spring rates are about 60lbs/inch.
So go through that list and you get.
Front
Code Red - 688-705 - 57- 59
Code White - 708-725 - 59 - 61
Code Green - 728-745" 60 - 62
Rear
Code Red - 613-631 - 51 - 52
Code White - 633-648 - 52 - 54
Code Green - 650-666 - 54 - 55
All the bold are in lbs/inch.
