BMW Drivetrain Parts for MINI

Clear BMW chassis

Please ensure your correct model is selected

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.

Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.

78mm Diameter with fitment for M12 nuts/bolts.

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. A limited lifetime warranty is provided, ensuring that these LSDs are free of defects in materials and workmanship upon receipt of the product and professional installation. Any part returned must be determined by MFactory Competition Products to be defective before any warranty credit or replacement is issued.

MFactory Competition Products's obligation under the warranty is limited to repairing or replacing, at its discretion, any part proven defective. The customer is responsible for prepaying transportation charges.

It's important to note that the final determination of the suitability of the products for the intended use is the sole responsibility of the buyer. MFactory Competition Products shall not be liable for any special, direct, indirect, incidental, or consequential damages, including claims for delay, loss of profits, or labor that might be claimed as a result of the failure of any part.
