Powerflex PFF5-1901G Caster Adjustable Front Radius Arm to Chassis Polyurethane Bushes (Pair) for BMW 2 Series F22/F23 | Front Control Arm Suspension Bush Upgrade

Transform steering feel and front-end bite on your BMW 2 Series

Upgrade the front axle compliance on your BMW 2 Series F22 and F23 with Powerflex PFF5-1901G adjustable caster bushings. Supplied as a pair, these uprated polyurethane mounts replace the soft factory items at the front tension strut to body location for crisper turn-in, better stability under braking and rock-solid geometry control on fast road or track.

Part number: PFF5-1901G | Pack contents: 2 bushes | Diagram ref: 1

Why this upgrade works

• Dial in precision: on-car caster adjustment of approximately ±0.75 degree allows you to fine tune steering self-centring and high-speed stability.
• Stronger control: around 60 percent stiffer than stock rubber in Road Series specification to reduce unwanted arm movement and keep alignment consistent.
• More grip where it counts: extra caster yields increased negative camber on lock for improved tyre contact, sharper turn-in and confident cornering.
• Refined yet responsive: high quality polyurethane provides excellent NVH manners while delivering a much tighter, more connected front end.
• Confidence built in: Lifetime Warranty from Powerflex for long-term peace of mind.
