Drivetrain Mounts and Upgrades

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.

At Turner we are very familiar with the N55 and B58. These are the new generation engines that you you can pull quite a bit of power from quite easily, if you want to put the power to the pavement the factory bushings and reinforcement just wont cut it. With soo many performance parts available for the turbocharged engines, it is very easy to make power but keeping the car under control can be another story. Reduce wheel hop, extend the life of your bearings, and add stability to your chassis!

Our in-house engineers created a solution to help transfer the power to the ground, the result is a simple yet astounding improvement to the performance of your vehicle. The rear diff brace helps put power down by reducing wheel hop and preventing losses during power transfer. With the added rigidity the rear end feels tighter for high speed applications and will extend the life of your choice of OE or aftermarket bushings.

Soft factory rubber differential bushings absorb vibrations between the chassis and differential, providing comfort and softness for normal driving conditions. As these bushings wear you will experience lackluster performance/response and they will need to be replaced. You can extend the life of these bushings while providing increased chassis stability with our differential brace for your F chassis. Add new poly differential bushings for an even better experience (T#:656153)

Note: Drilling is required for installation

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!

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). When paired with our flex-free solid transmission mounts you'll get smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid engine mount unless a corresponding solid transmission mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • Precision machined billet 6061-T6 aluminum housing
  • Black anodized for durability and corrosion resistance
  • Grade 10.9 stud - fear not, big turbo owners
  • Engineered in-house and made in America

Rubber engine and transmission mounts for a street car and solid aluminum for the track, right? Well, it's not that straightforward anymore.

Stock rubber fluid-filled mounts are designed to be soft and comfortable, limiting the NVH (noise, vibration, and harshness) felt by the driver. The drawback inherent with a conventional design is driveline deflection, making it more difficult to put the power to the wheels, as well as making a money-shift or miss-shift more likely as they age. Solid mounts are exactly the opposite of this - they permit tons of NVH while offering zero deflection, making these a must have for track-driven vehicles looking to capitalize on every ounce of performance available. Enthusiasts looking to find the best of both worlds often look to polyurethane engine mounts - and many are disappointed with other designs on the market. Seeking a mount that offers a positive connection yet doesn't deform, fail, or rattle the fillings out of their mouths is frequently a lost cause.

Until now. 

We engineered these mounts with these very concerns in mind. We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration. Understanding that heat is a concern for the passenger side mount's close proximity to the exhaust, we utilize a PEEK thermal insulation plate to greatly reduce heat transfer to the polyurethane, making heat a non-issue for these mounts. 

We offer two durometers, with both densities offering similar "positive connection" feeling. 60A is slightly softer and offers more of a stock feel, while 80A delivers a little more engine "feel" while under acceleration. 

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • High quality polyurethane offered in both 60A & 80A durometers (rebuildable, too)
  • Resistant to water, ozone, and chemicals, maintaining its resiliency and elasticity longer than conventional rubber.
  • Precision machined billet 6061-T6 aluminum housing, black anodized for durability and corrosion resistance. Grade 10.9 stud - fear not, big turbo owners.
  • Thermal isolation spacer on the hot side to resist heat transfer into the poly
  • Engineered in-house and made in America

Made in the USA TMS E90/E92/E82 (NON M) solid differential mounts are designed around current Grand Am Cup regulations, derived from, and currently used in TMS racecars. Thick Delrin casings are used as the non-metallic solid bushing. Replacing your differentials rubber mounts with this kit will result in a snappier feel when cornering and better suspension performance. You save money by never having to replace the stock rubber mounts that fail due to old age and fatigue. These bushings are CNC machined in the USA and made with high-grade materials.

These solid differential bushings/mounts fit the following BMWs:

Harness unused potential. Drive with confidence. Engineered to maximize strength and cooling performance while utilizing the unused secondary factory differential mount for enhanced support and driveline stability.

Our Turner Motorsport Dual-Mount Differential Cover is purpose-built to reinforce one of the most critical components in the G8X M3/M4 drivetrain. From the factory, BMW includes a secondary bushing location in the rear subframe but leaves it unused. Our solution fully capitalizes on this overlooked feature, giving the differential a second point of support for improved rigidity, reduced movement, and enhanced driveline response under load.

This cover is more than just a mounting upgrade. It’s precision-machined from 6061-T6 billet aluminum for exceptional strength without unnecessary weight. An aggressive fin profile improves thermal efficiency, helping to lower fluid temperatures in high-stress environments. Inside, the cover features an embossed channel that mirrors the ring gear path, ensuring fluid stays in contact where it's needed most, improving cooling and lubrication in all conditions.

Whether you're carving corners on the street or pushing the limits on track, this differential cover is designed to keep your rear end cool, stable, and responsive.

Key Features and Benefits:

The dual-mount design utilizes the factory-provided secondary bushing location, adding critical support to reduce differential deflection, extend bushing life, and minimize wheel hop.
CNC-machined from 6061-T6 billet aluminum, offering high strength and a precise fit.

Designed for track drivers, drift enthusiasts, and drag racers alike, this all-in-one driveline upgrade eliminates the factory weak points and reinforces your drivetrain for high-performance abuse. Whether you're laying down 500HP, clutch-kicking through corners, or launching hard at the strip, this cover keeps your differential secure, cool, and ready for battle.

The stock E30 differential cover features a single mounting provision—fine for a stock M20, but guaranteed to fail on your boosted high-horsepower M5X build. After years of broken covers, mounting tabs, and dreams, our team of E30 enthusiasts engineered the ultimate fix.

Unlike the brittle OEM cast aluminum cover, our upgraded differential cover is CNC-machined from 6061-T6 billet aluminum, offering a 30% increase in material strength alone. More importantly, a secondary mounting ear has been integrated into the design for added support, drastically improving stability and driveline shock absorption. The secondary mount is tied into the chassis using a reinforced sheet metal bracket and a billet aluminum plate, allowing for bolt-on installation or welding for ultimate rigidity.

Another major flaw of the factory E30 differential cover is its lack of any cooling provisions, leading to overheated fluid and premature wear. Our engineers solved this issue by incorporating advanced cooling features into the design. Large external fins have been added to the cover, and are optimized using CFD (Computational Fluid Dynamics) analysis to efficiently dissipate heat, reducing overall fluid temperatures. By maintaining a more stable differential temperature, this cover ensures consistent performance and extends the lifespan of your differential fluid. A built-in air duct assists in cooling by increasing airflow around the differential, further preventing heat-related failures. Our cover features optional -6AN fittings, allowing for easy integration of an external fluid cooler if desired. Finally, a 1/8 NPT port is included with the kit to ensure compatibility with fluid temperature monitoring systems.

Precision-machined from 6061-T6 billet aluminum and finished with a black hard coat anodizing, this cover is built to withstand hard use. Despite its robust construction and superior durability, this differential cover retains factory mounting features. This means any E30 188mm differential cover bushing can be installed, allowing you to tailor our upgraded cover to your build. The cover also accommodates large rear sway bars, ensuring fitment on cars with upgraded suspension. Our proprietary removable air duct provides easy access to sensor bungs, fill plugs, and drain plugs, making differential service a breeze.

FEATURES

Unmatched Strength & Durability - Heavily reinforced mounting locations are designed to withstand extreme horsepower, torque, and shock load. Secondary Differential Mount - A built-in secondary mount, integral sheet metal bracket, and billet adapter plate make this the strongest E30 differential cover on the market. Bolt-On or Weld-On Installation - The secondary mount is designed for easy bolt-in installation or can be welded to the chassis for ultimate rigidity. Optimized Cooling - Large external fins, designed using CFD analysis, dissipate heat efficiently, reducing overall differential fluid temperatures. Integrated Breather System - An integrated breather system reduces internal cavitation by properly venting built-up pressure. Enhanced Fluid Management - Includes a 1/8 NPT sensor port for real-time fluid temperature monitoring, and optional -6AN fittings for adding an external fluid cooler. Aerodynamic Air Duct - The included aerodynamic air duct further reduces fluid temperatures, increasing fluid service life and reliability. KIT CONTENTS

Made in the USA For our Grand-Am Cup E46 M3s we wanted a fully solid differential mount setup. The advantages of a fully-solid aluminum set is that they last forever, quickens response in the suspension, and frees up horsepower to the wheels. These fully solid aluminum diff mounts are CNC machined and lightened for a direct replacement of the original rubber pieces.

By substituting aluminum for rubber we can take out all of the deflection and 'wind up' inherent to the original rubber pieces. The high deflection rate of the stock rubber means the suspension reacts slower as the bushing is compressed. The power used to compress that bushing is instead passed straight to the axles and wheels. And since there is no time lost to deflection, response is greatly improved. These diff mounts are only recommended for racecars since the aluminum transfers more noise and vibration.

This is a 3-piece set with a single front bushing and two rear bushings to press into the cover. They mount with the stock BMW hardware.

This item fits the following BMWs:
2001-2006 E46 BMW M3

Rubber engine and transmission mounts for a street car and solid aluminum for the track, right? Well, it's not that straightforward anymore.

Stock rubber fluid-filled mounts are designed to be soft and comfortable, limiting the NVH (noise, vibration, and harshness) felt by the driver. The drawback inherent with a conventional design is driveline deflection, making it more difficult to put the power to the wheels, as well as making a money-shift or miss-shift more likely as they age. Solid mounts are exactly the opposite of this - they permit tons of NVH while offering zero deflection, making these a must have for track-driven vehicles looking to capitalize on every ounce of performance available. Enthusiasts looking to find the best of both worlds often look to polyurethane engine mounts - and many are disappointed with other designs on the market. Seeking a mount that offers a positive connection yet doesn't deform, fail, or rattle the fillings out of their mouths is frequently a lost cause.

Until now. 

We engineered these mounts with these very concerns in mind. We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration. Understanding that heat is a concern for the passenger side mount's close proximity to the exhaust, we utilize a PEEK thermal insulation plate to greatly reduce heat transfer to the polyurethane, making heat a non-issue for these mounts. 

We offer two durometers, with both densities offering similar "positive connection" feeling. 60A is slightly softer and offers more of a stock feel, while 80A delivers a little more engine "feel" while under acceleration. 

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • High quality polyurethane offered in both 60A & 80A durometers (rebuildable, too)
  • Resistant to water, ozone, and chemicals, maintaining its resiliency and elasticity longer than conventional rubber.
  • Precision machined billet 6061-T6 aluminum housing, black anodized for durability and corrosion resistance. Grade 10.9 stud - fear not, big turbo owners.
  • Thermal isolation spacer on the hot side to resist heat transfer into the poly
  • Engineered in-house and made in America

Made in the USA If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. We originally developed these mounts for E36 and E46 World Challenge racing but they also work perfect in BMW Modified and SCCA club racing and SpecE46 (SE46). These are machined from solid aluminum and have zero deflection. The engine torque will cause a rubber or urethane mount to flex or deflect. The stiffer the material the less movement there is and the more torque is passed through the driveline (instead of being wasted winding up the mount). At the transmission end the flex-free solid mounts will give smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We have designed these mounts so the engine is 5mm lower and the transmission is 1mm lower than the factory mounts. This helps lower the center of gravity for better balance and handling. We very strongly recommend using the transmission and engine mounts together as a complete kit. Mixing a rubber mount with a metal mount will cause undue stress on the mouting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used. This kit fits the E36, E46, Z3, and Z4 6 cylinder models listed below, including M3 models.

These are a no-compromise design for all-out racing use. Full solid aluminum mounts should not be used on street-driven cars. Because there is no material to absorb vibration these will be quite harsh for regular street use (track cars don't care about noise).

Subframe reinforcement kits are very strongly recommended to go along with these solid motor mounts to reduce the risk of damage to the subframe. The motor mount section of the subframe should be reinforced to prevent stress and failure of the subframe.

This item fits the following BMWs:

Modern BMW's are beginning to leave the performance derived handling and power delivery in the past as the demand for more comfort and features rises. The stiff suspension components designed around having the best driving experience from a luxury car has been left for the M models and replaced with soft rubber bushings and mounts. Unfortunately, this is a good move by BMW to support the masses.

The obvious approach was to offer products so the modern BMW can be upgraded into the car the enthusiast desires, superb handling, control, and a direct delivery of power to the rear wheels. When you upgrade to our Delrin subframe mounts you reconnect that power with almost zero negative feedback.

The added appeal to someone looking to take one of these machines on the race track is Delrin can be used when solid mounts are needed and aluminum is not an option with strict regulations found in??Grand-Am, BMW CCA, and other racing series.

Product features:

  • Precision machined Delrin(TM) 150 bushings.
  • Precision machined 6061-T6 aluminum inserts.?
  • Class legal for any racing class that does not allow a solid subframe bushing.?

Performance Benefits:

  • Eliminates subframe movement for more direct throttle and suspension? response.?
  • Minimizes wheel hop due to subframe deflection and movement.?

?

NOTE: We suggest replacing 3 of BMW # 31126760203 during installation Kit comes supplied with M14 mounting bolt, thread locker, and a Powerflex keyring. With the newer F8x M2/M3/M4's making big power and having superb chassis straight from the showroom, it's no wonder they're often found at the most serious of track-days or at tuning shops around the globe. Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicles' suspension components- most notably the rear differential bushings. Despite having alloted for two mounting bushings on the factory tubular subframe, BMW opts to use only a single offset bushing in the rear to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn out and softer than they once were. With hard launches and sudden and frequent on-off throttle changes, the single rear OE rubber bushing is subject to extreme torsional and directional forces, resulting in rapid degradation with failure often seen at around the 30,000-40,000 mile mark, and an unsettled and potentially clunky rear-end. The PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminum, and is designed to utilize the secondary mounting position on the OE subframe. With the addition of a second bushing, this prevents the diff from twisting under load, providing benefits such as: Reduced drivetrain movement Improved throttle response A more controlled and consistent chassis response to acceleration/deceleration Improved tire-to-road power transfer due to reduced wheel hop Reduced strain on bushings The corrosion-resistant, satin black, anodized aluminum bracket is optimized for high stress and deflection while withstanding high torque loads, but serves the same purpose in road-use and track-use cars with either a single OE bushing or dual aftermarket bushings. Although the bracket can be fitted without the need to remove the subframe from the vehicle completely, we would strongly recommend combining Powerflex products by using our already hugely popular 80A durometer PFR5-4026 Rear Diff Rear Mounting Bushings for both rear mounting positions alongside our PFR5-4025 Rear Diff Front Mounting Bushings in the front for the ultimate in differential control and a lasting street or track solution.

The Powerflex Rear Sway Bar Bushing - 18.5 mm Street for the BMW X3 (2003-2010) is a premium suspension upgrade designed to replace the factory rubber bushings with high-performance polyurethane. This bushing specifically fits rear sway bars with a 18.5 mm diameter, providing better durability and handling for street-focused driving.

Product Features:

  1. The Powerflex Rear Diff Front Mount Bushing - Flat Type for the BMW E38 7 Series and E39 5 Series is a premium suspension component designed to replace the factory rubber bushing in the front mount position of the rear differential. This high-performance polyurethane bushing is engineered to enhance drivetrain stability and improve overall vehicle performance, making it an ideal upgrade for drivers seeking longevity and sharper handling.

    Product Details:

    1. Flat-Type Design: This bushing is built with a flat-type design, which ensures a direct replacement fit for the factory-installed bushing in the front mount of the rear differential. It aligns perfectly with the BMW E38 and E39 chassis, providing an accurate and secure fit without the need for modifications.

    2. Polyurethane Material: Powerflex bushings are constructed from high-quality polyurethane, which offers superior durability compared to traditional rubber. This material is highly resistant to wear, heat, and degradation from oils and road contaminants, ensuring that the bushing remains effective for a much longer period under both normal and performance driving conditions.

    3. Enhanced Drivetrain Control: The rear diff front mount bushing plays a critical role in controlling the movement of the rear differential during acceleration, deceleration, and cornering. Powerflex's polyurethane bushing limits excessive movement and reduces drivetrain flex, leading to more consistent power delivery, reduced differential "clunking," and a smoother, more precise ride.

    4. Improved Handling: By stiffening the front mount of the rear differential, this bushing enhances the stability and control of the rear suspension, particularly during aggressive driving. Drivers will notice a reduction in body movement and improved handling characteristics, allowing for more confident cornering and better overall vehicle dynamics.

    5. Direct Replacement for OEM Bushings: Designed to replace the original rubber bushing without any additional modifications, this bushing fits seamlessly into the existing suspension setup of the BMW E38 7 Series and E39 5 Series. Installation is straightforward, and the bushing is engineered to match the factory specifications while offering a significant performance upgrade.

    6. Long-Lasting Durability: Polyurethane bushings are designed to withstand harsh conditions and prolonged use, far outlasting the OEM rubber components. This bushing resists cracking, warping, and deterioration over time, ensuring that it maintains its structural integrity and performance even after years of use.

    Advantages:

    • Increased Drivetrain Stability: Reduces differential movement, providing a smoother and more stable power transfer to the rear wheels.
    • Better Handling Response: Enhances rear-end control during acceleration, deceleration, and cornering, improving overall vehicle dynamics.
    • Long-Lasting Material: Outlasts rubber bushings, offering a cost-effective, long-term suspension upgrade.
    • Direct OEM Fitment: Simple replacement with no modification required, ensuring an easy installation process.

    Fitment:

    • BMW E38 7 Series (1994-2001)
    • BMW E39 5 Series (1995-2003)

    Key Benefits:

    • Reduced Drivetrain Slack: Minimizes play in the rear differential, eliminating clunks and improving overall ride quality.
    • Durable and Resilient: Made from high-performance polyurethane that resists damage from road debris, oils, and extreme temperatures.
    • Perfect for Daily or Performance Driving: Balances improved handling with everyday comfort, making it a suitable upgrade for both street and spirited driving.

    For BMW E38 7 Series and E39 5 Series owners looking for a reliable, long-lasting upgrade, the Powerflex Rear Diff Front Mount Bushing - Flat Type delivers improved handling, enhanced drivetrain control, and a more responsive driving experience. This is a vital upgrade for maintaining the performance and reliability of your rear suspension system.
