This steel E30 front control arm is a direct replacement for the original part and is the OEM Lemforder brand.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings.

Upgrade your drivetrain performance with ECS Tuning Performance Polyurethane Differential Bushings—engineered specifically for BMW F8x/G8x models and designed to deliver superior power transfer, durability, and driving precision.

Factory rubber differential bushings are built for comfort, absorbing vibrations between the differential and chassis during everyday driving. However, they are a known wear item that degrade over time—especially under spirited or aggressive driving conditions. Many F8x/G8x owners experience premature cracking and wear, leading to excessive drivetrain movement, reduced throttle response, and unwanted wheel hop.

ECS Tuning’s in-house engineered polyurethane differential bushings provide a high-performance solution to these common issues. By significantly reducing drivetrain deflection, these upgraded bushings enhance throttle response, improve handling stability, and minimize wheel hop—resulting in a more connected and controlled driving experience.

Constructed from durable 95A durometer red polyurethane and paired with precision CNC-machined 6061-T6 aluminum sleeves, these bushings are built to withstand extreme driveline forces while maintaining street-friendly comfort. Unlike solid or delrin mounts, ECS polyurethane bushings strike the perfect balance between performance and daily drivability—delivering increased rigidity without excessive noise, vibration, or harshness (NVH).

Whether you're carving canyon roads, launching at the drag strip, or simply commuting, these performance differential bushings ensure more efficient power delivery from the differential to the wheels—giving you better throttle modulation, traction, and overall control.

Key Features & Benefits:

Performance polyurethane differential bushings for BMW F8X models
Reduces drivetrain movement and improves power transfer
Enhances throttle response and minimizes wheel hop
95A durometer polyurethane for optimal balance of performance and comfort
CNC-machined 6061-T6 aluminum inserts with Type II black anodizing for corrosion resistance
Resistant to oil, chemicals, ozone, and road salt for extended service life
Designed to handle high torque loads and extreme driving conditions
Engineered using real-world load data and worst-case operating scenarios
Maintains street-friendly NVH levels compared to solid mounts
Replace worn factory bushings with ECS Performance Polyurethane Differential Bushings and experience tighter handling, improved drivetrain response, and long-lasting reliability.

ECS Tuning Lowering Springs undergo rigorous development and testing. The ECS Research & Development team ensures each spring set meets the highest standards of precision and durability by subjecting springs to extensive long-term testing in diverse conditions.

Enhanced Performance:

Designed exclusively for the xDrive E90 chassis, these linear coil springs offer a balance between performance and comfort, with spring rates only slightly higher than factory settings. This makes them ideal for daily driving while providing the enhanced dynamics sought by performance enthusiasts.

Additional Upgrades:

Maximize your vehicle's potential by pairing your lowering springs with our flush kit or spacer set. This combination further eliminates unwanted wheel gap, perfecting your E90's stance. Explore our extensive selection of wheel spacers for the ultimate customization.

Transform your E90 xDrive with ECS Tuning Lowering Springs, and enjoy the perfect synergy of performance, comfort, and style.

The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of rubber with a metal sleeve insert. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.

This is a replacement stock RIGHT FRONT (Passenger's side) control arm bushing with the mounting bracket.
