Powerflex Adjustable Front Radius Arm to Chassis Bush Caster for BMW F20 F21 F22 F23 F30 F31 F32 F33 F34 F36
Part number: PFF5-1901G
Upgrade your BMW F-Series suspension with the Powerflex Adjustable Front Radius Arm to Chassis Bush Caster. Built in Powerflex Road Series polyurethane and engineered to be approximately 60% stiffer than the original rubber bush, this adjustable caster bush resists deflection under load for sharper steering response, improved stability and confidence on fast road driving.
PFF5-1901G provides an on-car adjustable ±0.75 caster offset. Dial in extra caster for crisper turn-in and added negative camber on lock, giving improved tyre contact during hard cornering. This is a direct replacement for tired OEM bushes and a proven performance handling upgrade for BMW 1 Series, 2 Series, 3 Series and 4 Series F-models.
Why choose Powerflex PFF5-1901G
- Adjustable caster correction ±0.75 for precise alignment tuning
- Road Series polyurethane construction for durability and performance
- About 60% stiffer than OEM rubber to reduce unwanted suspension flex
- Improves steering feel, stability and turn-in on road and fast-road use
- Enhances tyre contact on cornering for predictable grip
