Bilstein B6 struts are the upgrade for a 2021-2022 BMW M440i Coupe that feels soft rather than broken. They keep the OE springs and ride height and simply take the slop out of how the car moves.
Bilstein invented the monotube gas damper and has been building suspension in Germany since 1954. Every unit is built to the same standard the company supplies to the manufacturers themselves, and it is backed by a limited lifetime warranty.
