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

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.

Are you tired of the traditional white DRLs that came with your BMW from the factory? Upgrade your headlights with the new Turner Motorsport LED DRL Modules to achieve the highly sought-after Yellow DTM or GT-style appearance!

Turner Motorsport LED DRL Modules offer the first true Plug-and-Play solution for your BMW, allowing you to easily swap them out without damaging your original DRLs. Unlike many options that require you to remove your DRL modules and pry the LED circuit board away from the factory heatsink—risking a bent circuit board and cracked traces—Turner Motorsport’s modules come with a pre-mounted heatsink. This design eliminates the risk and saves time on installation. Plus, if you ever need to revert back to stock, simply swap the modules out and you’re good to go.

These LED DRL modules are designed to work with the factory headlight controllers and wiring. No coding or additional wiring is necessary for a seamless integration.

This kit includes all the DRL modules necessary to upgrade both the driver and passenger side headlights.

Installation Note: Due to the location of the factory modules, removal of the fender liners and/or front bumper may be necessary.

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)

Still have the factory exhaust fitted to your B58? You don't know what your missing. Free up lost performance with a new full cat-back exhaust complete with factory valve control!

The B58 engine earned the badge "Worlds 10 Best Engines" four times as of 2023. In 2016 the single turbo straight six found its way to the leaderboards for the first time and followed up in 2017, 2019, and 2020 staying on the charts as one of the best engines in the WORLD.

Our new cat-back exhaust is designed to take out restrictions, maximize flow and give your B58 a signature exhaust note that will excite you on every drive. From the factory your vehicle comes equipped with a combination of three mufflers and resonators that do a great job of silencing the exhaust and restricting flow. There is a center muffler(one restriction), rear section resonator(two restrictions) and a bulky muffler(three restrictions!). With all of those stop gates how do you expect to get the maximum performance out of your vehicle, you simply cannot do so. Lucky for our in-house engineers you no longer have to deal with the quiet and limiting factory exhaust.

To create a cat-back exhaust for this incredible engine the changes happen right after the downpipe. We replaced the factory oval pipe with our full 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep flow to a maximum! With smooth mandrel bent transitions our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature B58 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Dual 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

B58 Engine Design:

BMW's first mass produced turbo charged engine, the N54 took the world by storm opening a whole can of worms in the car industry and aftermarket community. A new era of motors were created with the new B58 roughly 9 years after the N54 had been tested and pushed to its limits along with its single turbo companion, the N55. In 2015 the modular engine family was created and the B58 was released into the wild to set a new standard in performance and reliability. Turning back to their roots the B58 engine features a closed-deck engine design similar to the N54 that allows a massive increased in boost pressure capacity and heightened compression ratio. Thought the B58 is similar in weight and size to its predecessor, the new modular engine makes considerably more power right off the rip. With the new block design heat management has been upgraded to reduce the affects of heat cycling to slow the rate of cooling and prevent engine components from failing due to rapid cooling. Just like the N55 the B58 comes fitted with dual vanos, valvetronic and a single twin scroll turbo. Just 8 years experience of this motor we can all agree that the B58 looks like it could be the future of motors to come. This tunable engine has been tested up to 1000hp with the stock block and hosts a platform for the community to break into a whole new class of attainable "supercar killers".
