Description
Powerflex Rear Subframe Front Bushings for BMW 3 Series (E46) / Z4 / X3.
Function and design
Subframe and beam mounts connect a suspension-carrying assembly to the body. Their compliance affects how that assembly moves relative to the chassis under braking, cornering and driveline loads.
What to consider
A replacement bushing and a reinforcement insert are different approaches to that mounting point. Changes in isolation can make road or drivetrain noise more noticeable; select the construction and specification appropriate to the build.
Application
BMW 3 Series (E46) / Z4 / X3.
Technical details
- Construction: replacement mounting bushing. Confirm the original housing or bracket arrangement; a bushing listing does not imply that a complete mount or bracket is included.
Choose your series
- Street: the road-oriented series; compound selection depends on the individual application.
- Black Series: the firmer series generally intended to prioritize movement control. Product-specific fitment and intended-use restrictions still apply.
