Powerflex PFF5-1901G Caster Correction Adjustable Bush Kit - Front Lower Control Arm Rear/Radius Arm to Chassis Poly Bushes (Pair) for BMW F-Series F20 F21 F22 F23 F30 F31 F32 F33 F34 F36 1 2 3 4 Series - Tension Strut/Thrust Arm/Wishbone - Road Series

Adjustable front tension strut to body bushings for BMW F-Series 1, 2, 3, 4

Part number: PFF5-1901G

Sharpen your BMW’s front end with these adjustable front tension strut to chassis bushings. Manufactured by Powerflex in their Road Series polyurethane and engineered to be around 60% stiffer than the factory rubber mounts, they dramatically cut unwanted arm movement, giving cleaner steering feedback, better straight-line stability and more confidence on fast road driving.

On-car adjustability of +/- 0.75 caster lets you fine tune geometry for crisper turn-in, improved self-centring and increased negative camber on lock, helping the tyre contact patch stay planted under hard cornering and braking. A direct swap for tired OEM thrust arm bushes, this upgrade is a proven way to reduce vagueness at the wheel and make your F-series BMW feel tighter and more precise.

Highlights

• On-car caster adjustment +/- 0.75 for precise alignment tuning
• Approx 60% stiffer than standard rubber to resist deflection under load
• Road Series polyurethane for durable, long-lasting performance
• Cleaner steering input, improved turn-in and a more planted front axle
• Direct replacement for the front lower control arm rear mount position

We have fitted these bushes in-house and customer feedback has been consistently positive, with noticeably sharper steering, stronger braking stability and a more connected feel compared to worn original parts.
