Subframe Bushings for BMW 1 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. 

Designed to work with the original bushing and eliminate over compliance or better known in motorsport as 'lost motion' of the rear crossmember. This Whiteline kit dramatically reduces rear cross member misalignment and movement which allows a more positive feel from the rear end during cornering.

Features:

• Performance - Whiteline's engineered "Synthetic Elastomer" bushings feature the quality ride of rubber at lower speeds and at higher speeds react when under cornering, accelerating and braking loads, for CHASSIS CONTROL and improved handling.
• Durable - The advanced synthetic elastomer characteristics ensure superior elasticity, memory and outright durability for all forms of driving applications!
• Resistant - Whiteline's synthetic elastomer formulation boasts resistance to oil, grease, ozone and weathering
• Lubricant - Supplied with extreme pressure molybdenum disulphide (LM) based grease (where required) for extended life.
• Installer Friendly - Designed with the installer in mind by reducing the need of specialized skills, tools and equipment.
• Black - The neutral (black) appearance favored by restorers and racers.
• Lifetime Warranty - All Whiteline bushing kits are backed by a lifetime warranty
