Powerflex Black Series Front Radius Arm Inner Mounts for BMW 5 Series E60 E61 xDrive

Part Number: PFF5-2101BLK

Dial in precision and stability on your xDrive 5 Series with this Powerflex Black Series 95A polyurethane upgrade. These motorsport-grade front radius arm to body bushings replace the soft factory rubber at the inner mounting point, cutting unwanted movement, tightening up steering feel and keeping your alignment consistent under cornering and braking. Ideal for track days, fast road builds and competition use, this is the go-to uprated polybush kit for enthusiasts who want crisp turn-in and dependable geometry control.

We have installed this setup at MJ Modifications and feedback from owners has been excellent. Expect a more connected front end, improved braking confidence and repeatable handling when pushed hard.

Why this upgrade

• 95 Shore A Black Series compound for maximum stiffness and minimal deflection
• Cleaner steering inputs with better on-centre feel and response
• Holds caster and toe more accurately under load for predictable handling
• Resistant to oil, salt and road grime for long service life
• Direct replacement for the original inner mounts, no permanent mods required
• Perfect for fast road, time attack and track-focused E60 and E61 builds
