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.

Elevate your E90 xDrive with ECS Tuning Lowering Springs, engineered for unparalleled handling and sleek aesthetics. Designed for enthusiasts who demand the perfect blend of performance and comfort, these springs offer a lowered stance and enhanced driving dynamics.

Key Benefits:

Improved Handling: Experience superior cornering and steering feedback with a lower center of gravity, reducing body roll and enhancing road-holding capability. Sporty Aesthetics: Achieve a cleaner, more aggressive look by minimizing wheel gap, giving your E90 a "fitted" appearance. Comfortable Ride: Linear-style springs maintain an OEM+ ride quality, balancing sportiness with everyday drivability. Specifications:

Front Lowering: 1.0" - 1.2" Rear Lowering: 1.2" - 1.3" Front Spring Rate: 505 lbs/in Rear Spring Rate: 854 lbs/in Finish: High-quality flat black powder coat to prevent corrosion. Precision Engineering:

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.

Urethane mounts keep the differential from twisting under load. As torque is put through the driveline it causes anything to twist and move. The differential is mounted to the subframe and the twisting and deflection can be transferred to the rest of the chassis. With a stiffer mount the differential will not deflect as much. This improves seat-of-the-pants feeling to the driver, giving more feedback for smoother power delivery. In theory, there's also more torque being sent to the drive wheels since it's not being used up shifting the diff weight around.

These are tough 88A durometer urethane bushings with a anodized almunum center sleeve, engineered by ECS. This is a set of E36 diff bushings - 1 for the front and 2 for the rear cover. New high-grade hardware is included (the front bolt has a tendency to snap from all that torque twisting!).
