BMW Drivetrain Parts for BMW 4 Series F32 (2014+)

At Turner we are very familiar with the N55 and B58. These are the new generation engines that you you can pull quite a bit of power from quite easily, if you want to put the power to the pavement the factory bushings and reinforcement just wont cut it. With soo many performance parts available for the turbocharged engines, it is very easy to make power but keeping the car under control can be another story. Reduce wheel hop, extend the life of your bearings, and add stability to your chassis!

Our in-house engineers created a solution to help transfer the power to the ground, the result is a simple yet astounding improvement to the performance of your vehicle. The rear diff brace helps put power down by reducing wheel hop and preventing losses during power transfer. With the added rigidity the rear end feels tighter for high speed applications and will extend the life of your choice of OE or aftermarket bushings.

Soft factory rubber differential bushings absorb vibrations between the chassis and differential, providing comfort and softness for normal driving conditions. As these bushings wear you will experience lackluster performance/response and they will need to be replaced. You can extend the life of these bushings while providing increased chassis stability with our differential brace for your F chassis. Add new poly differential bushings for an even better experience (T#:656153)

PRODUCT DEVELOPMENT

Turner F Chassis Differential brace was designed, engineered, tested and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer and rigorous long term product testing.

The ZF 8-speed automatic transmission (8HP) has become the go-to choice for performance enthusiasts, delivering lightning-fast shifts, impressive torque handling, and ample tuning potential. However, the stock transmission pan falls short in critical areas. Its plastic construction, integrated non-replaceable filter, and limited fluid volume leave little margin for error in demanding conditions.

To address these limitations, we've engineered a premium solution: a cast aluminum transmission pan that boosts durability, cooling performance, and serviceability. Designed with enthusiasts in mind, this upgraded pan increases fluid capacity by 1 liter to reduce transmission temperatures and improve long-term reliability, even under aggressive driving or track conditions.

Built to outlast and outperform the OEM plastic pan, the aluminum construction resists damage from road debris and eliminates the risk of cracking. Our pan is hard-coat anodized in black for superior corrosion protection and a long-lasting finish that looks as good as it performs.

Our aluminum pan upgrade is engineered to work seamlessly with the OEM G8X 8HP transmission filter (24007855263), allowing for easy and cost-effective fluid service. Integrated magnets help to trap metal particulate, extending the life of your transmission by keeping contaminants out of the fluid.

Key Features:

Cast aluminum construction offers superior strength and resilience over the OE plastic pan

Increased fluid capacity (+1L) enhances thermal management and reduces the risk of overheating

Serviceable design uses the OEM G8X transmission filter for easy, affordable maintenance

Hard coat anodized finish provides exceptional corrosion resistance and longevity

Integrated magnets collect metallic debris, protecting transmission internals

Kit Includes:

Turner Motorsport ZF 8HP High-Capacity Aluminum Transmission Pan
OE Hengst G8X Filter Installation Kit
Installation:

Vehicle plastic belly pans may vary. Because the Turner 8HP transmission pan is taller to allow for increased fluid capacity, some vehicles may require trimming of the plastic belly pan, or the belly pan may need to be installed over the transmission pan where it may make contact.

Turner Motorsport Lightweight N55 Flywheel & Upgraded Clutch Kit

Unlock the full potential of your N55-powered BMW with our performance-driven clutch and flywheel kit. Designed to enhance daily drivability while delivering increased power handling and improved throttle response, this kit is the ultimate upgrade for enthusiasts seeking more from their vehicle.

Why Choose This Kit?
This setup features the Turner Lightweight N55 Flywheel, precision-engineered for quicker acceleration, faster rev-matching, and a more responsive driving experience. Paired with an upgraded OE clutch from the high-performance 335is and F10 550i(V8 Bi-Turbo), this combo is capable of handling over 500 ft-lbs of torque while maintaining smooth, factory-like engagement and durability.

The factory dual-mass flywheel may prioritize smoothness and efficiency, but it comes at the cost of responsiveness and is prone to failure in high-performance applications.
