Upgrading various parts of the differential can have tremendous benefits in your car's performance. It's easy to forget that the differential is a source for making your car faster and handle better so it's often overlooked. The engine is not the only place to make the car faster. Our differential options vary from gearing upgrades to limited slip conversions. You can purchase the ring & pinion gear sets on their own (professional installation required) or have us build a diff around your own specifcations. The options are almost endless! Every custom-built diff is fully rebuilt with seals and bearings. We also design and supply bushing options to reduce driveline wind-up, finned differential covers for better cooling, and more!

Ratio Changes - Changing the differential gearing is one of the best and most-effective upgrades you can make on any BMW (old or new). By using a shorter (numerically higher) final drive ratio you are increasing your RPM relative to road speed - this puts you in a more powerful RPM range than before! Since you're in a 'meatier' part of the power band you're now putting down more power/torque to the ground. If you can trade outright top speed for faster acceleration at daily speeds then this is the perfect upgrade for you.

Limited Slip Upgrades - Sadly, many BMWs today are not equipped with a limited slip (posi-traction) differential. BMW has tried to compensate by using traction control that cuts power at the engine or applies the brakes to retard wheel spin (or a combination of both). But nothing beats the function and feel of a a true LSD which may be why BMW continues to use them in M cars. Our LSD upgrades can be done a number of different ways - a factory-type limited slip unit with either 2 or 3 clutch packs, helical type, OS Giken unit, or something truly custom. We can also vary ramp angles and setup to change the limited-slip behavior under acceleration, deceleration, and cornering. Need a custom diff? Call or e-mail to have a quote.

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.

Features and Benefits of Powerflex Rear Differential Rear Bushings:

  • 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.

Installation Considerations:

  • 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.

Applications:

  • BMW E60 (5 Series)
  • BMW E63 (6 Series)

Ideal For:

  • 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.
