Powerflex PFF5-1903-30 Polyurethane Front Anti-Roll/Stabilizer Sway Bar Bushes/Bushings 30mm (Pair) for BMW 1 Series F20/F21 2011-2019 - ARB Mounts Upgrade Kit

Powerflex PFF5-1903-30 Front Stabiliser Bar Bushings 30 mm for BMW 1 Series F20 F21 2011 to 2019

Transform the front-end feel of your BMW 1 Series with this uprated polyurethane front bar bushing kit. Part number PFF5-1903-30 is designed for a 30 mm front stabiliser bar and replaces tired factory rubber with durable performance urethane that keeps geometry consistent, sharpens steering and helps the car corner flatter on fast road or track.

We run these bushings on our own builds and have installed them for many customers. The feedback is always the same, quicker turn in, better front axle grip and a more planted, confidence-inspiring drive. If your 1 Series feels vague, wanders under braking or shows uneven tyre wear, worn ARB mounts are a common culprit. This is the cost-effective fix that lasts.

Why this upgrade

• Immediate improvement in steering accuracy and response
• Reduces roll compliance to keep tyres in contact with the road
• Maintains alignment under load for predictable handling
• Ideal for fast road, spirited driving and occasional track days
• Polyurethane construction resists oil, grime and abrasion for long life
• Low NVH characteristics when installed and lubricated correctly
• Backed by the Powerflex Lifetime Warranty
