I noticed today that my coil springs have two different markings on them. The rear springs are marked with a green circle while the fronts have a reddish/brown square. I find it odd that BMW would mark them differently. Any 6-cyl Sport package owners want to take a look and see if all 4 corners have the same or different markings? Also, if you could give the year of your car, that would be great. Thanks! :)

Your springs are not only custom to the sport package, but also vary based on what options are on the car.
