Drivetrain Mounts and Upgrades for BMW F83 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!

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.

Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.

Features & Benefits:

Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:

Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:

Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.
