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.

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.

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.
By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.
Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.
Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

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.
