For BMW E30, Z3, E21, and 2002 models, upgrading to adjustable rear trailing arm bushings from manufacturers like Powerflex offers both improved performance and the ability to fine-tune suspension alignment. These bushings are designed to replace the factory rubber bushings, which can degrade over time and lead to imprecise handling.

Key Features and Benefits:

  • Adjustable Alignment: These adjustable rear trailing arm bushings allow you to modify rear toe and camber settings. This is crucial for fine-tuning the suspension for different driving styles, especially if the car is used in motorsport applications like track days or autocross, or if the car has been lowered and needs suspension corrections.
  • Superior Handling: By significantly reducing the play in the rear trailing arms, these bushings improve the car’s handling dynamics. They keep the rear suspension more rigid during acceleration, braking, and cornering, resulting in sharper, more predictable handling.
  • Polyurethane Durability: Unlike the OEM rubber bushings, which wear out over time due to heat, road grime, and chemicals, these adjustable bushings are made of durable polyurethane. This material resists aging, cracking, and wear, ensuring consistent performance over a longer period.
  • Reduced Deflection: Adjustable polyurethane bushings limit suspension deflection, allowing the vehicle to maintain optimal suspension geometry under load. This improves cornering performance and reduces body roll.
  • Longer Service Life: Polyurethane bushings are known for their longevity compared to rubber bushings, offering a "fit and forget" solution for car owners who want reduced maintenance and better overall reliability.

Installation and Adjustment:

  • Direct Fit Replacement: These bushings are designed as a direct replacement for the stock rubber bushings, offering the same fitment while adding adjustability. No major modifications are typically required, making installation easier for those familiar with suspension work.
  • Alignment Precision: Once installed, these bushings allow precise adjustments to the suspension alignment, which is ideal for correcting issues that arise from modifications like lowering the vehicle or installing performance suspension components.

Ideal for:

  • BMW E30 (3 Series)
  • BMW Z3
  • BMW E21 (3 Series)
  • BMW 2002

These adjustable rear trailing arm bushings are perfect for enthusiasts looking for more control over their vehicle’s alignment and handling, whether for street driving or performance applications. They offer a great balance of increased performance, durability, and adjustability without sacrificing daily driving comfort.

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.
