The rear damping adjuster on coilovers is usually hidden under a bunch of hard to reach interior panels requiring you to remove carpet, panels and sometimes even the rear seat back in order to adjust the dampening on your BC rear coilovers. The BC Racing rear extender adjuster allow you to make these adjustments without removing the rear interior. Simple make two small holes in the interior above the adjuster and the extension can be passed through the interior panels. Now the adjustments can be performed from above.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

The Powerflex silicone grease is the only lubricant we suggest for long, squeak free operation. The lubricant contains silicone that resists heat and water and keeps a more constant viscosity to allow it to stay in the bushing as temperatures increase. The lubricant also does not lose it's lubrication properties over time like an anti-seize type lubricant. Each pack will lube 2 large bushings or 4 small.

    • Designed specifically for the BMW G80 M3 and G82/G83 M4, these bushings contribute to a more precise suspension setup, allowing for sharper steering and improved driver feedback. This is crucial for both track performance and spirited driving on the road.

  3. High-Quality Construction:

    • Typically made from durable polyurethane, these bushings are engineered to withstand the demands of high-performance driving. They offer improved longevity and resistance to wear compared to stock rubber bushings.

  4. Improved Handling Dynamics:

    • By minimizing bushing deflection, these components help maintain optimal suspension geometry, resulting in enhanced stability, reduced body roll, and better traction during aggressive maneuvers.

  5. Direct Fitment:

    • Specifically tailored for the G80 M3 and G82/G83 M4 models, these bushings ensure a perfect fit and seamless integration with the existing suspension system.

  6. Installation Considerations:

    • Installation involves removing the radius arm from the suspension assembly. While some experienced enthusiasts may choose to perform this upgrade themselves, professional installation is recommended for precise alignment and performance tuning.

Benefits of Upgrading to Caster Adjustable Bushings:

  • Customizable Handling: The ability to adjust the caster angle allows drivers to personalize their vehicle's handling characteristics, accommodating various driving styles and conditions.
  • Enhanced Stability: Improved caster settings can lead to greater straight-line stability and control, particularly beneficial during high-speed driving.
  • Increased Steering Precision: Less flex in the bushings translates to more responsive steering and an overall more connected driving experience.

In summary, the BMW G80 M3 and G82/G83 M4 Front Radius Arm Bushings (Caster Adjustable) are an excellent upgrade for drivers seeking to enhance their vehicle's handling and performance. With adjustable caster capabilities, these bushings offer improved stability, precision, and a more engaging driving experience, making them ideal for both everyday use and track applications.
