The Powerflex Rear Subframe Rear Mount Insert for the BMW E39 5 Series is specifically designed to enhance the performance and stability of the rear suspension system. By utilizing high-quality polyurethane, this insert significantly improves the rigidity of the rear subframe, offering a range of benefits for driving enthusiasts.
Enhanced Handling Performance: The insert reduces flex in the rear subframe mount, resulting in improved stability during cornering. This enhancement leads to better handling characteristics, allowing for more precise control and confidence when navigating turns.
Durability and Longevity: Constructed from resilient polyurethane, these inserts are designed to withstand harsh driving conditions and resist wear from oil, heat, and environmental factors. This durability ensures they maintain performance over a longer period compared to traditional rubber mounts.
Improved Road Feel: By minimizing unwanted movement in the subframe, these inserts provide enhanced feedback to the driver, allowing for a more connected and engaging driving experience. This is particularly beneficial for spirited driving and performance applications.
Straightforward Installation: Designed for a direct fit into the existing rear subframe mounts of the E39 5 Series, these inserts allow for easy installation without the need for modifications or extensive labor.
Ideal for BMW enthusiasts looking to upgrade their E39 5 Series's suspension system, these inserts deliver improved handling and responsiveness, making them suitable for both everyday driving and high-performance scenarios.
Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.
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 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.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.
Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

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.
