Can Bilstein B6 EDC dampers improve the E92 M3?

It’s no secret that we love the E9x M3, and have long thought that for UK road usage BMW M pretty much nailed the suspension tuning on the Competition Package to the point that we never messed with it. But as these cars age the dampers are starting to fail, and OEM replacements are pretty pricey. Bilstein make a B6 damper that is EDC compatible - Could it not only repair a failed damper for less money, but also improve the cars excellent road manners? We fitted a set to our Japan Red KA401 to find out!
