Powerflex PFF5-1903-30 Front Stabiliser Bushings — BMW 4 Series F32 F33 F36 — 30 mm Pair

Part number: PFF5-1903-30

Give your BMW 4 Series a sharper, more planted front end with these uprated Powerflex front stabiliser bar bushings. Replacing tired rubber mounts with high-performance polyurethane brings noticeably tighter steering, reduced roll and more confidence on B-roads and track days. We use this exact setup on our own builds and our customers love the immediate improvement in turn-in and mid-corner stability.

Why this upgrade makes a difference

• Firmer bar-to-chassis location for cleaner steering feedback and quicker response
• Helps control body movement for improved cornering grip and predictable handling
• Polyurethane resists deformation and ageing better than OE rubber for long-term consistency
• Improves road holding and tyre contact, supporting safer, more stable braking
• Excellent value over time compared with frequently perishing rubber mounts
• Backed by the Powerflex Lifetime Warranty for peace of mind

If your factory bushes are soft or worn, you may notice vague front-end feel, knocking over bumps, uneven tyre wear or instability under braking. Upgrading to these performance bushings restores geometry control so your BMW tracks straight, turns crisply and feels more connected to the road.
