Powerflex BMW Drivetrain Parts for BMW F83 M4 S55 3.0L

Clear BMW chassis

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

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.

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.

Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience. Powerflex is pleased to introduce their new S55 Engine Mount Inserts, intermediate alternatives to the BMW aluminum inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in Yellow 70A durometer material, they are designed to fit the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: Sharper throttle response Improved gear shifting More direct power transfer More balanced on/off throttle handling Prolonged life of the OE mounts A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted.
