BMW Differential and Gearing Upgrades

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.

When high torque loads and aggressive corner exits push your chassis to the limit, stock differential mounts quickly become the weak link. The ECS Tuning Rear Differential Front Mount Upgrade Kit is track-engineered to lock down your rear diff, control axle wrap, and ensure immediate power delivery to the pavement.

Built to withstand severe track abuse, this kit eliminates hardware failure by replacing the undersized factory M12 bolt with an ultra-high-tensile Grade 12.9 M14x1.5 bolt. Surrounding the upgraded hardware is a track-spec 95A durometer red polyurethane bushing and a rugged 6061-T6 aluminum sleeve finished in Type II black anodizing. Engineered for maximum drivetrain stiffness, this upgrade ensures your differential stays precisely aligned under the harshest motorsport conditions.

Note: Upgrading to M14x1.5 hardware requires drilling and tapping the original M12x1.5 differential mounting hole. See T#58563042 for a complete kit that includes the proper-sized drill and tap.

As Used on our Project Mini Cooper S
The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How? By getting the power to the ground! The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on all MINI's, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

The BMW F10/F07 Rear Diff Rear Mount Bushing by Powerflex is a specialized upgrade designed to replace the OEM rubber bushings in the rear differential mount. Here's a breakdown of its key features and benefits:

  1. Durability and Longevity: Made from high-quality polyurethane, these bushings are significantly more resistant to wear compared to the stock rubber, which tends to degrade over time due to heat, oils, and mechanical stress.

  2. Enhanced Performance: The stiffer material reduces flex in the rear differential, ensuring more precise power transfer to the wheels. This results in better acceleration response, reduced wheel hop, and improved handling characteristics, especially during aggressive driving.

  3. Reduced Differential Movement: The stock bushings can allow excessive differential movement under load, leading to a less stable rear end. The Powerflex bushings minimize this movement, enhancing the overall driving dynamics.

  4. Balanced Comfort and Performance: While polyurethane bushings are firmer than rubber, Powerflex designs their bushings to maintain a balance between performance and comfort. This means less increase in vibration, noise, and harshness (NVH) compared to other aftermarket bushings, making them suitable for both daily driving and performance applications.

  5. Custom Fit for BMW F10/F07: Specifically engineered for the BMW 5 Series (F10) and BMW 5 Series GT (F07), these bushings offer a precise fit, ensuring easy installation and compatibility with factory components.

Overall, the Powerflex Rear Diff Rear Mount Bushing is a go-to upgrade for those looking to improve their BMW’s rear-end stability, responsiveness, and durability without sacrificing too much comfort.

Differentials serve the key purpose of transmitting power from the driveshaft to the axles. Factory rubber bushings absorb some of this power to allow for cushy, comfortable acceleration, at the expense of performance. Many OEM differential bushings are fast-wearing and failure-prone, resulting in driveline slop and thunks when shifting or going over bumps. Your E36 Evo M3 will improve in: Improved Handling and Stability - Upgrading to an aftermarket rear differential front mount bushing can do wonders for your car's handling and stability. These bushings are designed with performance in mind, reducing unwanted movement of the differential. Reduced Wheel Hop - Wheel hop can be a drag, both figuratively and literally. An upgraded front mount bushing helps minimize wheel hop, especially during hard acceleration or aggressive driving. Say goodbye to that unsettling bounce and hello to smoother power delivery. Powerflex polyurethane differential bushings are firmer than OEM rubber bushings, eliminating associated driveline slop and allowing for the crisp application of power to the ground, resulting in better throttle response and control. 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. The use of Powerflex Copper Grease PCG1 is recommended for ease of installation. Periodic reapplication is recommended to extend the squeak-free service life of bushings. Powerflex Black Series bushings are the ultimate in track and race bushings. Need bushings for a car that's street-driven? Powerflex street bushings are an ideal alternative for street-driven vehicles and those that see occasional autocross or track time. Fits these BMW models: E36 Evo M3

The BMW F10/F07 Rear Diff Front Mount Bushing from Powerflex is a performance-enhancing replacement part designed for the rear differential mounting system. Here are its main features: Polyurethane Construction for Longevity: Made from high-quality polyurethane, these bushings outperform traditional rubber bushings by resisting wear from heat, oils, and road contaminants. This means they provide a longer service life, reducing the need for frequent replacements. Enhanced Power Transfer: By limiting excess differential movement, the stiffer Powerflex bushings allow more precise power transfer to the rear wheels. This results in sharper throttle response and improved overall drivetrain efficiency, especially during spirited driving. Increased Rear-End Rigidity: The factory rubber bushings allow for some differential movement, which can lead to instability. The Powerflex bushings reduce this flex, resulting in a more stable and predictable rear end, particularly when cornering or under heavy acceleration. Improved Handling and Stability: With reduced play in the differential mounting points, the rear suspension geometry stays more consistent. This translates to sharper handling, better grip in corners, and a more connected driving experience, making the vehicle feel more composed. Controlled NVH (Noise, Vibration, and Harshness): Powerflex engineers their bushings to strike a balance between performance and comfort. While polyurethane is stiffer than rubber, these bushings are designed to minimize the increase in NVH, ensuring that the ride remains comfortable for daily driving while still benefiting from enhanced performance. Direct Fitment for BMW F10/F07: These bushings are specifically designed for the BMW 5 Series (F10) and BMW 5 Series GT (F07), providing an easy, direct replacement for the original equipment. This ensures compatibility and smooth installation. The Powerflex Rear Diff Front Mount Bushing is ideal for BMW enthusiasts seeking to upgrade their vehicle's rear differential stability and performance, particularly for high-performance driving or in modified cars.
