SPL Parts Rear Lower Control Arm Inner Bushing BMW M2 (F87) / M3 (E9X/F80) / M4 (F82/F83)

Eliminate Deflection. Maximise Cornering Grip.

Precision-engineer your rear suspension with SPL Parts Rear Lower Control Arm (RLCA) Inner Bushings. These high-performance replacements swap the large, compliant factory rubber bushings for low-friction, PTFE-lined spherical bearings. By upgrading the connection between the lower control arm and the subframe, you eliminate the deflection and binding that occurs under heavy cornering and acceleration loads.

Standard rubber bushings distort under load, causing "dynamic" changes to your camber and toe settings. These SPL bushings preserve your desired geometry throughout the suspension's range of motion, providing a more stable and predictable rear end. To ensure maximum longevity and reduced NVH (Noise, Vibration, and Harshness), SPL utilises the largest possible F1-spec FK bearings, offering a maintenance-free, self-cleaning solution for both street and competitive track use.

Key Features

• Improved Rear Grip: Maintains a consistent tyre contact patch by preventing unwanted geometry changes during hard cornering.
• Eliminate Binding: Low-friction spherical design allows the arm to pivot smoothly through its travel compared to the resistance of bonded rubber.
• F1-Spec Bearings: Features the largest available PTFE-lined FK spherical bearings for high load capacity and quiet operation.
• Precision Machined: 6061-T6 aluminium bearing shells and spacers ensure a perfect fit and high corrosion resistance.
• Maintenance-Free: Self-lubricating and self-cleaning bearing design requires no periodic greasing.
• Made in the USA: Engineered and manufactured for professional-grade performance.
