Drivetrain Mounts and Upgrades for BMW F82 M4 S55 3.0L

Clear BMW chassis

Please ensure your correct model is selected

From the factory, engine and transmission mounts are rubber and thus a wear component. Worn out engine or transmission mounts create sloppiness and a disconnect between the driver and your BMW's powerplant. If your vehicle is purpose built for the track, we recommend solid engine and transmission mounts. These have zero deflection, but come at the expense of added NVH (noise, vibration, and harshness). Poly engine and transmission mounts offer a good balance between OEM rubber and solid mounts for those with mixed purpose vehicles, offering great performance and connection with little sacrifice in terms of NVH.

Increase drivetrain rigidity and put that power to the ground! This industry-leading encapsulated design reduces NVH and prevents heat transfer.

From the factory, all BMW models are equipped with soft rubber or fluid-filled engine mounts. While these mounts perform well at isolating drivetrain vibrations, they are prone to degradation and allow for significant drivetrain movement. This often results in a loose-feeling driveline, missed shifts, and a generally disconnected driving feel.

To address these issues, We have developed a performance alternative. Constructed from 6061 Billet Aluminum, these mounts are built to last. While most performance drivetrain mounts feature solid or polyurethane-bonded aluminum construction, the engineers at Turner designed a unique four-piece design that disburses NVH (noise, vibration, and harshness). This multi-piece design offers the added benefit of serviceability. Additionally, encapsulating the polyurethane and adding a TecaPeek isolator prevents heat transfer to the insert, increasing the lifespan and durability of the mount.

Features & Benefits:

High-strength 6061 billet aluminum construction
80A Polyurethane provides a considerable increase over stock rubber durometer, eliminating excess deflection and ensuring drivetrain stiffness.
Instead of the typical polyurethane-bonded aluminum construction, this mount is encapsulated to reduce NVH (noise, vibration, and harshness).
Finished in black hard-coat anodized for a clean, durable, and corrosion-resistant finish.
TecaPeek isolator reduces heat transfer from the engine to the mount insert, increasing the lifespan of the mount.
A simple bolt-on design makes for an easy install
Replace your worn-out factory engine mounts and experience increased drivetrain rigidity, reduced deflection, and more precise shifting. Our Turner Performance Polyurethane Engine Mount Set is designed for maximum durability and strength while maintaining the perfect balance between stiffness and comfort—the perfect choice for your high-horsepower BMW!

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.

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.

Differential bushings are responsible for keeping your rear end planted during the delivery of power to the rear wheels. As these bushings age, they wear out and should be replaced. If you ever see your bushings are cracked, it is time to replace them. By eliminating the drivetrain deflection that factory rubber bushings permit, throttle response is improved, and the tendency for a car to “Wheel Hop” is significantly reduced. Upgrade to ECS Poly Diff Bushings and feel the difference!

The rear subframe bolts on the M2/M3/M4 are one-time use only and need to be replaced any time they are removed, such as during a diff install, sway bar install, bushing replacement, or any time the subframe is removed. Re-using the original bolts may damage the threads inside the body so make sure you have new M2/M3/M4 subframe hardware on hand for any work.

Instead of completely replacing the mount, simply make a billet aluminum insert for them. This leaves the feel of the factory mount in place but stiffens them up quite a bit removing unwanted engine movement without rattling your teeth out or emptying your wallet.
