BMW Drivetrain Parts for BMW G82 M4 S58 3.0L

Our Turner Motorsport rear shifter bushing is a precision-engineered solution designed to eliminate excessive deflection in the factory BMW G8X shift carrier assembly. The OEM rubber bushing introduces unwanted compliance that translates to a vague shifter feel, imprecision under load, and potential gear misalignment during aggressive driving. This polyurethane and billet aluminum replacement addresses that with a focused approach to both material selection and mechanical function.

Our engineer replaced the soft rubber isolator with a 70A durometer polyurethane bushing housed in a CNC-machined 6061-T6 aluminum body. The result is a significant reduction in bushing deflection while retaining the necessary articulation for BMW’s dual-bushing shift carrier design. Strategically placed relief cuts in the poly insert allow controlled movement without compromising rigidity where it matters most, translating to a more direct, confident shift feel without introducing harsh NVH into the cabin.

By maintaining stock geometry and compatibility with OEM components, this bushing installs as a direct replacement for BMW part #25118623459, with no modification required. Ideal for spirited street driving, track use, or anyone seeking a more mechanical and connected shift experience.

Technical Specs:

70A polyurethane construction for optimal stiffness-to-compliance ratio
CNC-machined 6061-T6 billet aluminum housing
Type II anodized for corrosion resistance
Retains dual-axis articulation of factory shift arm
Direct fitment for G80 M3 / G82 M4 / G87 M2 (with manual transmission)
Performance Gains:

Drastically reduces lateral and fore-aft play in the shifter
Improves shift precision, especially under load or high-RPM shifts
Minimizes missed shifts and sloppy gear engagement
Maintains daily drivability with near-OEM NVH levels
Whether you’re chasing lap times or just want your daily to feel more dialed in, this rear shifter bushing is a must-have for restoring and upgrading the mechanical precision BMW’s manual platform deserves.

If you’re looking to take things a step further, adding our Dual Shear Selector Rod and Short Shifter is a great way to build on this upgrade and unlock even more shift feel and precision—whenever you’re ready

Harness unused potential. Drive with confidence. Engineered to maximize strength and cooling performance while utilizing the unused secondary factory differential mount for enhanced support and driveline stability.

Our Turner Motorsport Dual-Mount Differential Cover is purpose-built to reinforce one of the most critical components in the G8X M3/M4 drivetrain. From the factory, BMW includes a secondary bushing location in the rear subframe but leaves it unused. Our solution fully capitalizes on this overlooked feature, giving the differential a second point of support for improved rigidity, reduced movement, and enhanced driveline response under load.

This cover is more than just a mounting upgrade. It’s precision-machined from 6061-T6 billet aluminum for exceptional strength without unnecessary weight. An aggressive fin profile improves thermal efficiency, helping to lower fluid temperatures in high-stress environments. Inside, the cover features an embossed channel that mirrors the ring gear path, ensuring fluid stays in contact where it's needed most, improving cooling and lubrication in all conditions.

Whether you're carving corners on the street or pushing the limits on track, this differential cover is designed to keep your rear end cool, stable, and responsive.

Key Features and Benefits:

The dual-mount design utilizes the factory-provided secondary bushing location, adding critical support to reduce differential deflection, extend bushing life, and minimize wheel hop.
CNC-machined from 6061-T6 billet aluminum, offering high strength and a precise fit.
Built-in cooling fins increase surface area for improved heat dissipation and lower differential fluid temperatures.
Internally contoured to follow the ring gear profile, promoting consistent fluid coverage and effective lubrication.
Maintains a 1.1-liter fluid capacity, closely matching OEM specifications for ease of servicing.
Integrated -6 AN ports support the addition of an external differential cooler for increased fluid volume and extended service intervals.
Compatible with the factory differential fluid temperature sensor and includes provisions for 1/4” NPT aftermarket sensors.
Product Development:

Like all Turner Motorsport performance solutions, this differential cover was developed in-house by our dedicated Research and Development team. Designed, engineered, tested, and quality-inspected using advanced tools including FARO laser scanning for reverse engineering, SolidWorks 3D CAD modeling, in-house rapid prototyping, and extensive long-term testing, you can trust that this part meets the highest standards of fit, function, and durability.

From spirited street driving to full-throttle track days, the Turner Motorsport Dual-Mount Differential Cover ensures your G8X delivers the response, strength, and cooling capacity it needs when it matters most.
