Motorsport-grade front arm bushes for BMW F10 F11 F06 F12 F13 xDrive
Unlock sharper steering, tighter turn-in and rock-solid braking stability with these Powerflex Black Series polyurethane front arm bushes. Built from a 95A durometer compound, they dramatically reduce compliance in the front tension strut/thrust arm, keeping your alignment true under hard cornering and heavy braking. Expect a more connected front end, consistent geometry and a confident, precise feel on fast road, track day and competition builds.
Why upgrade
- Precision control: limits flex in the front lower arm-to-body mount for stable caster and toe under load
- Stronger than rubber: 95 Shore compound resists deformation, heat and oil for long-term performance
- Improved feedback: crisper response through the wheel without the vagueness of ageing OE bushes
- Direct fit: replaces the factory mount with no change to geometry
What you get
- 2 x polyurethane bushes (pair) - one car requires 2
