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.

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.

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.

The Powerflex Black Series Rear Diff Front Mount Insert for the BMW F22 (2 Series), F30 (3 Series), and F32 (4 Series) is a robust and high-performance bushing designed for motorsport and aggressive driving. It's part of Powerflex’s Black Series line, which prioritizes precision and control by using a stiffer polyurethane material to enhance the vehicle's dynamics.
Material and Hardness: Made from 95A durometer polyurethane, the Black Series is much firmer than standard bushings, designed specifically for track use. This stiff material drastically reduces unwanted movement in the differential mount.
Enhanced Driving Precision: By reducing flex in the front differential mount, this insert enhances throttle response, reduces wheel hop, and sharpens the overall feel of the drivetrain. This results in better power transfer and improved handling during aggressive acceleration, hard cornering, and rapid gear changes.
Durability: Unlike OEM rubber mounts, which can degrade over time due to exposure to heat, oil, and general wear and tear, Powerflex’s polyurethane inserts are built to withstand harsher conditions, offering greater longevity and reliability.
Simplified Installation: The insert is designed to fit into the existing OEM mount, making installation relatively straightforward without requiring complete replacement of the differential mount. This makes it an efficient and cost-effective performance upgrade.
Performance Trade-off: While the Black Series offers a significant performance boost, it can also slightly increase noise, vibration, and harshness (NVH) inside the cabin. This is a typical trade-off for stiffer, track-oriented mounts.
This insert is popular among BMW enthusiasts who want to upgrade their car’s handling for track days or spirited driving, making the rear-end of the car feel more planted and controlled.

For the BMW E60 (5 Series) and E63 (6 Series), upgrading to Powerflex rear differential rear bushings is an essential modification for enhancing the vehicle's performance, handling, and longevity. These bushings play a critical role in connecting the rear differential to the chassis, and their quality directly impacts the driving experience.
Premium Polyurethane Material: Powerflex bushings are crafted from high-grade polyurethane, offering superior durability and resistance to wear compared to stock rubber bushings. This material is less susceptible to degradation from heat, oil, and road grime, ensuring consistent performance over time.
Enhanced Differential Stability: Stiffer bushings help to reduce unwanted movement and flex in the rear differential, which is crucial for optimal power transfer to the rear wheels. This results in improved stability and better handling characteristics during acceleration and cornering.
Improved Handling Dynamics: By minimizing differential movement, Powerflex bushings maintain proper alignment and enhance the overall handling precision of the vehicle. This results in more responsive steering and improved cornering performance, providing a more engaging driving experience.
Reduced Noise, Vibration, and Harshness (NVH): While these bushings are firmer than the factory rubber components, they are designed to minimize NVH. This means you can enjoy improved performance without a significant increase in cabin noise or discomfort, making them suitable for both daily driving and spirited performance use.
Longevity and Reliability: Powerflex bushings are designed to withstand the rigors of performance driving without deteriorating over time. This durability translates to fewer replacements and reduced maintenance, making them a cost-effective upgrade in the long run.
Direct Fit Replacement: These bushings are engineered to directly replace the factory bushings without modification. This simplifies the installation process, though some technical knowledge and tools may be required to ensure proper fitment.
Professional Installation Recommended: Given the importance of the rear differential in the overall drivetrain, professional installation is advised. This ensures that the bushings are installed correctly and that the differential is properly aligned.
Performance Drivers: If you’re looking to enhance your BMW's handling and responsiveness, especially during spirited driving or track events, these bushings will provide a noticeable improvement in performance and stability.
Preventive Maintenance: Upgrading to Powerflex bushings is a proactive measure to ensure the longevity of your differential and related components. If you're noticing signs of wear or if your car is regularly subjected to high-performance conditions, these bushings are a worthwhile investment.
In conclusion, Powerflex rear differential rear bushings for the BMW E60 and E63 are a vital upgrade for enthusiasts seeking enhanced performance and durability. These bushings improve handling precision, increase stability, and contribute to a more engaging driving experience, making them an excellent choice for both everyday driving and high-performance applications.

The BMW F10/F07 Rear Diff Rear Mount Bushing by Powerflex is a specialized upgrade designed to replace the OEM rubber bushings in the rear differential mount. Here's a breakdown of its key features and benefits:
Durability and Longevity: Made from high-quality polyurethane, these bushings are significantly more resistant to wear compared to the stock rubber, which tends to degrade over time due to heat, oils, and mechanical stress.
Enhanced Performance: The stiffer material reduces flex in the rear differential, ensuring more precise power transfer to the wheels. This results in better acceleration response, reduced wheel hop, and improved handling characteristics, especially during aggressive driving.
Reduced Differential Movement: The stock bushings can allow excessive differential movement under load, leading to a less stable rear end. The Powerflex bushings minimize this movement, enhancing the overall driving dynamics.
Balanced Comfort and Performance: While polyurethane bushings are firmer than rubber, Powerflex designs their bushings to maintain a balance between performance and comfort. This means less increase in vibration, noise, and harshness (NVH) compared to other aftermarket bushings, making them suitable for both daily driving and performance applications.
Custom Fit for BMW F10/F07: Specifically engineered for the BMW 5 Series (F10) and BMW 5 Series GT (F07), these bushings offer a precise fit, ensuring easy installation and compatibility with factory components.
Overall, the Powerflex Rear Diff Rear Mount Bushing is a go-to upgrade for those looking to improve their BMW’s rear-end stability, responsiveness, and durability without sacrificing too much comfort.
