The problem with the BMW Performance suspension rates is that the rates you see discussed were estimated by Mr. 5 with a lot of assumptions and never tested on a bench. He also got the suspension with M-Sport dampers, while others in Europe get it with different dampers.
Also, different people receive different front springs depending on their car's options.
So the BMW Performance spring rates are not at all reliable (unless you have a better source for the rates than this estimation ?).
