As you can see in my posted link I compared the old springs to the new 560 SL springs in a pic with measurements. There is quite a difference.

Joel: Can you measure the height of the new and old springs for a comparison. I'm curious what the rears will come out to. I was told the new 380SL springs were the same height as 560s but less taught. Also, A pic would be great too. Thanks.

Rich: I'm not an expert but I doubt that the Diff mounts will make any obvious difference in height. Also, when I did the sub frame bushings I noticed no difference. The springs are where it's at.
