Powerflex PFF5-1902G Polyurethane Camber Adjustable Front Lower Control Arm/Wishbone Inner Rear Bushes (Pair) – Camber Correction Alignment Bush Kit for BMW 4 Series F32 F33 F36 (F3x) – Front Arm to Chassis/Body Mounts

Uprated poly bush kit with on-car camber correction for BMW 4 Series F32 F33 F36

Transform front-end response on your BMW 4 Series with this camber-correcting polyurethane bush pair. Designed as the inner lower wishbone mounts, these alignment-adjustable bushes replace the soft OE rubber, tightening up steering, improving stability under braking and helping you put more rubber on the road through every bend.

We fit these in-house at MJ Modifications and customer feedback is consistently excellent. Expect sharper turn-in, a more planted front axle and more consistent geometry on both fast road and track days, with minimal increase in NVH compared to tired factory bushes.

Why this upgrade makes a difference

• On-car camber tuning of approximately plus or minus 0.5 degrees for precise front-end alignment and better contact patch
• Stiffer polyurethane controls unwanted arm movement, boosting steering accuracy and confidence at speed
• More consistent braking and reduced tramlining compared with ageing rubber mounts
• Helps even out tyre wear and supports predictable cornering grip
• Durable, long-life solution backed by the Powerflex Lifetime Warranty
