These don't offer damper adjustments. At that price, I'd just go with Bilstein PSS, a proven name. If you want adjustability, though, then the BCs are the front runners even though their performance under stress remains to be seen (at least by the populace of M5Board).this will be a good competitor to the beloved BC Racing coils that are popular amongst us E39 beast owners, especially since it's made by KW.
