Description
Powerflex Front Control Arm Bushings for BMW 3 Series (E46) / BMW Z4 (E85/E86).
Function and design
A suspension arm bushing forms a controlled mounting point between the arm and its supporting structure. Compliance at that joint allows movement under load; the condition and construction of the bushing influence how consistently the arm locates the wheel.
What to consider
For a suspension refresh, replacing deteriorated mounting bushings addresses movement at the joint rather than changing the spring or damper rate. Final steering and handling behavior also depends on the remaining joints, tires and alignment.
Application
BMW 3 Series (E46) / BMW Z4 (E85/E86).
Bracket bore selection
The 60 mm and 66 mm dimensions refer to the mounting bracket bore that accepts the bushing, not the control arm diameter. Check the installed bracket. E46 M3 and Xi versions are separate applications, and a shared E46 generation name does not establish fitment.
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.
