The Bilstein B6 Performance front strut insert is a direct-fit performance replacement for rear-wheel-drive BMW E30 325i Convertible models using the factory 51mm strut housing. It installs inside the vehicle's existing front strut housing.

Compared with worn factory inserts, the B6 helps reduce front-end float, excessive brake dive, and vague steering response. It is a strong choice for a street-driven restoration or OEM+ suspension refresh that retains standard-height springs.
