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.

The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Helical LSD puts the power-to-the-ground and maximizes your vehicle's traction. A must for any car be it street, strip, or track.

What exactly does an LSD do you ask? Without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).

An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off-road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.

Features:

An industry first, 30-day Feel the Torque™ money back guarantee and a Limited-Lifetime Warranty!
Forged and Cryo-tempered
Advanced Shot Peening technology for increased surface hardness
Designed to withstand the extreme shock loads of competition-level drag racing
Maintenance-free gears eliminate the need for special fluid or rebuilds associated with typical plate LSDs.
Lock-free operation ensures no adverse steering response.
**As a break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.**

Includes $500 core charge to be refunded when we receive your rebuildable core.

    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 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 acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane 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.

    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.

    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 best way to gain a prominent advantage over the competition is to do it with the MFactory Metal Plate Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Plate LSD puts the power-to-the-ground and maximises your vehicle's traction. This 1-way differential will provide torque transfer only during accelleration. This set up works the best for the drag race minded drivers. What exactly does an LSD do you ask? Well without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have). An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling. Features: Forged and Cryo-Tempered for unsurpassed toughness Advanced Shot Peening technology for increased surface hardness Coil Spring preload system ensures minimal power loss and maximum response Lower initial pressure ensures maximum durability and chatter-free operation Fully rebuildable with adjustable lock (80-100%) and option for different cam types Cam type provides the option for 2 distinct levels of initial torque transfer Available in 1.0, 1.5, and 2.0 way options *Any defects or warranty clams will have to go directly to Team M Factory*

    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.

The smooth consistent distribution of power to the wheels with the MFactory Plate LSD puts the power-to-the-ground and maximises your vehicle's traction. This 1.5-way differential works similar to a 2-way in that it provides torque transfer during both accelleration and decelleration. However, the advantage over a 2-way is that it requires less force to lock the differential. This means that it will allow for different wheel speeds, like when cornering. A 1.5-way differential is typically the best option for track or street use, as it keeps from having one tire skipping or dragging. What exactly does an LSD do you ask? Well without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).

    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.

    video: E92 335i with limited slip

    click for high quality
    A turbocharged BMW such as the 135i or 335i needs traction to put that power to the ground. The stock differential of both the 135i and 335i only put power to one wheel -- this just won't cut it! Upgrading to a limited slip differential means power to BOTH wheels, for better lauch, acceleration, and track handling. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've used their products on our own Championship winning E46 and E92 race cars.

    With the 135i/335i LSD unit, they have incorporated revolutionary new ideas into the design (4 years in the making!) which uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. The end result of their efforts is the OS Giken's OS Super Lock LSD which offers incredible durability and reliability on street and track driven BMWs. The use of highest quality materials, precise machining, forged gears and sound engineering makes this LSD durable and reliable enough for road racing performance (which we can personally vouch for!). Zero break-in required. Super smooth and quiet engagement, and 100% progressive locking capability.

    Installation note: BMW differentials use many unique and BMW-only parts and components. Only technicians who are experienced and familiar with BMW parts should perform the installation. The OS Giken LSD is the limited slip unit (or 'chunk') only. It replaces the stock non-LSD chunk but the original ring and pinion and other internals must be installed with the OS Giken unit. This unit will only work on 335i manual differentials with a bolt-in or modified ring gear. Proper setup and spacing is critical for long life operation. Incorrect installation will void the warranty. We also offer the TCD unit pre-installed - see our performance diff catalog for more info.

    The OS Giken Superlock Diff unit fits the following BMWs:
    2008-2012 E82 BMW 135i with manual transmission

    A turbocharged BMW such as the 135i or 335i needs traction to put that power to the ground. The stock differential of both the 135i and 335i only put power to one wheel -- this just won't cut it! Upgrading to a limited slip differential means power to BOTH wheels, for better launch, acceleration, grip, and track handling. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've used their products on our own Championship winning E46 and E92 race cars.

    OS Giken's newest innovation is their quietest and smoothest limited slip unit yet - the Traction Control Differential (TCD). TCD is similar to their excellent Superlock differentials but with additional oil channels and pathways. The added lubrication makes diff operation smoother and quieter than before (not that there were many complaints to begin with). The locking engagement is more progressive than before which makes this diff more suitable for street driving. Track cars and drift cars should still use the Superlock LSD as it will transition to lock sooner. TCD is an evolution of a diff that was already extremely well-engineered for road and track use. Not willing to rest on their laurels, they took their superior engineering a step further.

    With the 135i/335i LSD unit, they have incorporated revolutionary ideas into the overall limited-slip design which uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat.
