Powerflex Black Series Adjustable Camber Front Arm-to-Chassis Polyurethane Bush (Wishbone/Radius Arm/Tension Strut Rear Bush/LCAB) for BMW F20 F21 F22 F23 F30 F31 F32 F33 F34 F36 1 2 3 4 Series incl. M135i M140i M235i 335i 340i 440i – PFF5-1902GBLK

PFF5-1902GBLK Adjustable Camber Polyurethane Bushings for BMW F-Series Front Lower Arm

Part number: PFF5-1902GBLK

Give your BMW F-series a sharper front end and repeatable alignment with motorsport-grade arm-to-body bushings. This camber-correcting solution replaces the tired rubber rear mount of the front lower arm with a high-durometer polyurethane assembly that resists deflection, tightens steering feel and lets you dial in extra negative camber for fast road and track use.

Why enthusiasts choose this upgrade

• On-car camber adjustment ±0.5 degrees for precise geometry tuning
• 8 percent stiffer than factory rubber to reduce flex under braking and cornering
• 95A Black Series polyurethane for maximum control of suspension kinematics
• Restores crisp turn-in, feedback and tyre contact patch stability
• Direct-fit replacement for the rearward front wishbone mount on BMW F20 F21 F22 F23 F30 F31 F32 F33 F34 F36

We run these on our own cars and customers consistently report a big step-up in steering response and confidence without the vagueness of worn OE bushes.

Technical highlights

• Compound: Black Series 95 Shore A polyurethane
• Adjustment range: plus or minus 0.5 degrees camber on the vehicle
• Enhances stability during heavy braking and high-load cornering
• Engineered to keep alignment true for consistent lap-after-lap performance
