Find Parts That Fit Your Vehicle

BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Unlike other aftermarket mounts, the mounting plate and studs of our mounts have been Zinc-plated to prevent corrosion. Rogue Engineering Transmission Mounts are sold as a pair, and come with Grade 8 Zinc plated hardware. Rogue Engineering transmission mounts are designed with street comfort in mind while still reducing left and right movement of the transmission. By using a cylindrical shape instead of the factory hourglass like design and utilizing Neoprene rubber deflection can be significantly reduced, minimizing unwanted transmission movement while maintaining vibration dampening characteristics.

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? 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.

One of the most satisfying upgrades you can make to your BMW is to its factory shifter mechanism. By reducing the shifter's throw, you can give your manual transmission BMW a sportier, more precise feel. However, with so many different "short shift kits" out there, how can you be sure you're making the right decision? With the introduction of the Rogue Engineering OCTANE short shift kit, the choice is now crystal clear!

Rogue Engineering refuses to compromise with "lever substitution" as a method of short shift kit development. Rather than using actual test vehicles for their products, some companies actually dig through OEM factory parts diagrams to determine which factory levers can be substituted with others. This "lever substitution" method of introducing product is unacceptable. These shift kits have been developed and perfected through years of experience in proven short shifter technology, by Co-Founder, Ben Liaw. As longtime BMW enthusiasts know, Ben was single-handedly responsible for introducing and developing the idea of affordable, BMW factory-like, short shift kits for late model BMWs (BL/SS for those young enough to remember!). 

Rogue Engineering idea of a short shift kit is not substituting levers in place of factory ones just because "they fit". Throughout the 80s until recently, BMW was notorious for using only a few specific shifter levers for their manual transmission vehicles. For other companies, making just a few "replacement levers" and offering them in place of those factory part numbers was an easy way of calling it a short shift kit. Unfortunately, for those companies, BMW started using many different part numbers making it more difficult to just "swap in a lever".

Rogue Engineering only develops it's short shift kit with test vehicles in their facility, testing numerous prototypes, offering others to test it before settling on its final design. They feel that this old school, real world testing is the best way when modifying OEM ergonomic, sensory-based controls.

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 maximizes your vehicle's traction. This 1.5-way differential works similarly to a 2-way in that it provides torque transfer during both acceleration and deceleration. 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.

Soft bushings are the enemy of launching hard, and keeping your drivetrain together. The BMW Transfer Case bushings are notoriously soft, and that is the opposite of what you want when launching a car hard. You can replace the bushing with a solid one, but this is time-consuming usually requires lowering or removing the transfer case, and results in a lot of added NVH. The best path is simply to reduce the amount of flex of the factory bushing so you keep the nice manners when cruising around town, and at idle, but when its time to the launch the transfer case cannot move as it could without the insert. These come as a set of two with 2 bolts to keep them in place. Install time once you get to them is about 2-3 minutes. Could not be easier. Put some lube on them, push them in, and tighten the screws. These are a MUST for high-power G8X, and F9X X3/X4M Builds. All platforms they fit are below. Features: 6061- T6 aluminum construction Easy to install Fully reversible Do not add NVH

One of the most satisfying upgrades you can make to your BMW is to its factory shifter mechanism. By reducing the shifter's throw, you can give your manual transmission BMW a sportier, more precise feel. However, with so many different "short shift kits" out there, how can you be sure you're making the right decision? With the introduction of the Rogue Engineering OCTANE short shift kit, the choice is now crystal clear!

Rogue Engineering refuses to compromise with "lever substitution" as a method of short shift kit development. Rather than using actual test vehicles for their products, some companies actually dig through OEM factory parts diagrams to determine which factory levers can be substituted with others. This "lever substitution" method of introducing product is unacceptable. These shift kits have been developed and perfected through years of experience in proven short shifter technology, by Co-Founder, Ben Liaw. As longtime BMW enthusiasts know, Ben was single-handedly responsible for introducing and developing the idea of affordable, BMW factory-like, short shift kits for late model BMWs (BL/SS for those young enough to remember!). 

Rogue Engineering idea of a short shift kit is not substituting levers in place of factory ones just because "they fit". Throughout the 80s until recently, BMW was notorious for using only a few specific shifter levers for their manual transmission vehicles. For other companies, making just a few "replacement levers" and offering them in place of those factory part numbers was an easy way of calling it a short shift kit. Unfortunately, for those companies, BMW started using many different part numbers making it more difficult to just "swap in a lever".

Rogue Engineering only develops it's short shift kit with test vehicles in their facility, testing numerous prototypes, offering others to test it before settling on its final design. They feel that this old school, real world testing is the best way when modifying OEM ergonomic, sensory-based controls.

When it comes to gaining a significant advantage over your competitors, the MFactory Helical Limited Slip Differential (LSD) is your ultimate ally. This LSD offers a seamless and consistent distribution of power to your vehicle's wheels, allowing you to harness maximum traction and put the power firmly on the ground.

But what does an LSD do, you ask? Well, without an LSD, your car essentially operates as a "1-wheel drive," as it can't deliver torque to both wheels simultaneously. Instead, it directs torque to the wheel with less grip, highlighting the limitations of an open differential, which is standard in most vehicles.

An LSD, on the other hand, permits the wheels to spin at slightly different speeds by a limited amount, typically represented as a percentage difference. It's when the differential locks that both wheels receive power. It's important to note that LSDs function differently from locked differentials, such as those in off-road trucks, which supply equal torque and rotational speed to both rear wheels simultaneously, often causing handling issues.

Key Features:

  • Crafted from imported Japanese SAE 4320 Steel
  • Industry-first 30-day "Feel the Torque™" money-back guarantee, along with a Limited-Lifetime Warranty
  • Forged, double tempered, and super sub-zero treated for unparalleled toughness
  • Utilizes advanced Shot Peening technology to increase surface hardness
  • Engineered to withstand the extreme shock loads of competition-level drag racing
  • Advanced gear geometry designed using industry-leading software, delivering more power to the ground
  • Exclusively uses the highest quality Brighton-Best Hardware
  • Maintenance-free gears eliminate the need for special fluids and rebuilds associated with plate-type LSDs
  • Ensures lock-free operation, preventing adverse effects on steering response
  • Rated for up to ~1000 WHp

As part of the break-in procedure, we recommend changing the fluid after the first 3-400 miles of use.

Warranty:

MFactory Competition Products stands behind the quality of its Helical LSDs.

VTT now offers the ONLY easy-to-install, plug-and-play xDrive controller on the market. This device will allow you to turn off and on your xDrive capability from the driver's seat with a remote. While other options do exist such as X-Delete, or an in-dash gauge, one is a very slow process and is not viable to use as a way to do a burnout at the drag strip, and the other is a very expensive, AND very intrusive device that requires removal of most of the dash, and installing a gauge. VTT's solution takes 30 seconds to install once you gain access to the underside of the vehicle, and can be removed just as easily.
