Bilstein B4 Front Strut Assembly with Mounts for BMW E64 645Ci 650i — Overview
These are OE-replacement front strut assemblies from Bilstein, built specifically for the E64 6 Series convertible - that means the 645Ci and 650i. The B4 line is Bilstein's factory-replacement spec, so you're getting their monotube gas-pressure damper technology at stock ride height and valving. Not a performance upgrade, but a serious step up in build quality over whatever worn-out ZF Sachs units you're pulling off a high-mileage 6er.
