BMW Suspension Parts for BMW 3 Series E30 (1984-1991)

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.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Engineered to perform, Powerflex performance polyurethane differential bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers. 

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

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 18mm Rear Sway Bar Bushings for the BMW E30, E28, and E24 are designed to replace the stock rubber bushings with high-quality polyurethane, optimizing the rear sway bar's performance. This upgrade is essential for enhancing handling characteristics and overall vehicle stability.

Key Advantages:

1. Superior Handling: The stiffer polyurethane construction minimizes flex in the sway bar, leading to reduced body roll and improved cornering performance, making the vehicle feel more planted during sharp turns.
2. Long-Lasting Performance: Unlike rubber bushings, these polyurethane options are highly resistant to wear, oil, and environmental elements, ensuring they maintain their effectiveness over time.
3. Enhanced Steering Precision: By reducing unwanted movement in the sway bar mount, these bushings provide a more direct and responsive steering feel, improving driver confidence.
4. Custom Fit for 18mm Bars: Specifically tailored for BMW models with an 18mm rear sway bar, these bushings offer straightforward installation and precise fitment.

These bushings are an excellent choice for BMW enthusiasts aiming to enhance the handling and durability of their E30, E28, or E24, suitable for both daily driving and spirited performance on the road or track.
