BMW Drivetrain Parts for BMW F83 M4 S55 3.0L

BMW’s Getrag GS7D36SG Dual-Clutch Transmission is a masterpiece of engineering. It's renowned for its rapid gear changes, robust construction, and direct, motorsport-inspired feel. While the transmission itself delivers exceptional performance, its supporting components don’t always keep pace. The factory plastic oil pan and limited oil capacity compromise cooling efficiency and long-term reliability, especially during high-performance use. With this in mind, we set out to engineer a solution that elevates durability, thermal management, and fluid control to match the transmission’s world-class performance.

We've designed a permanent, high-performance replacement for the flawed OEM pan: a cast-aluminum, increased-capacity upgrade that enhances cooling and durability. Its all-aluminum construction provides a significant upgrade over the OE plastic pan, which is prone to cracking when impacted by road debris. Engineered for those who demand more from their vehicle, our design increases fluid capacity to promote superior cooling and help maintain optimal transmission temperatures, even in the most demanding conditions.

To ensure a leak-free seal, we engineered a heavy-duty Viton gasket specific to their transmission pan design. The Viton material provides exceptional reliability under high temperatures and resists deformation—a common failure point of the factory rubber gasket. For further protection, integrated magnets actively attract and hold metal debris that could otherwise compromise the transmission's longevity. This innovative design keeps your fluid clean and extends the overall life of your drivetrain.

Whether your DCT-equipped BMW serves as a track car or a highway cruiser, this pan ensures your transmission remains cool and efficient, minimizing the risk of overheating and wear.

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

Increase drivetrain rigidity and put that power to the ground! This industry-leading encapsulated design reduces NVH and prevents heat transfer.

From the factory, all BMW models are equipped with soft rubber or fluid-filled engine mounts. While these mounts perform well at isolating drivetrain vibrations, they are prone to degradation and allow for significant drivetrain movement. This often results in a loose-feeling driveline, missed shifts, and a generally disconnected driving feel.

To address these issues, We have developed a performance alternative. Constructed from 6061 Billet Aluminum, these mounts are built to last. While most performance drivetrain mounts feature solid or polyurethane-bonded aluminum construction, the engineers at Turner designed a unique four-piece design that disburses NVH (noise, vibration, and harshness). This multi-piece design offers the added benefit of serviceability. Additionally, encapsulating the polyurethane and adding a TecaPeek isolator prevents heat transfer to the insert, increasing the lifespan and durability of the mount.

Features & Benefits:

High-strength 6061 billet aluminum construction
80A Polyurethane provides a considerable increase over stock rubber durometer, eliminating excess deflection and ensuring drivetrain stiffness.
Instead of the typical polyurethane-bonded aluminum construction, this mount is encapsulated to reduce NVH (noise, vibration, and harshness).
Finished in black hard-coat anodized for a clean, durable, and corrosion-resistant finish.
TecaPeek isolator reduces heat transfer from the engine to the mount insert, increasing the lifespan of the mount.
A simple bolt-on design makes for an easy install
Replace your worn-out factory engine mounts and experience increased drivetrain rigidity, reduced deflection, and more precise shifting. Our Turner Performance Polyurethane Engine Mount Set is designed for maximum durability and strength while maintaining the perfect balance between stiffness and comfort—the perfect choice for your high-horsepower BMW!

The factory BMW S55 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 26.5 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.

Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 18.5 lbs., this design significantly reduces rotational mass, allowing your S55 to achieve its true motorsport potential!

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.

Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.

Features & Benefits:

Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
