Turner recommends running drivetrain mounts of all the same variety - if you are using poly engine mounts, you should also use poly transmission mounts. This kit is your solution to make sure all components of your vehicle are working with each other to achieve the performance you're looking for. Polyurethane material is more resistant to water, ozone, and chemicals, maintaining its resiliency and elasticity longer than conventional rubber. Keep your vehicle planted for spirited driving while having crisper throttle response and reduce drivetrain movement along with wheel hop. Kit includes: Turner Engine Mount Set - 60A Polyurethane ECS Transmission Mount Set - Street 70A Polyurethane ECS Differential Bushing Set - 95A Polyurethane ECS Subframe Mount Set - 95A - Polyurethane

Made in the USA TMS E90/E92/E82 (NON M) solid differential mounts are designed around current Grand Am Cup regulations, derived from, and currently used in TMS racecars. Thick Delrin casings are used as the non-metallic solid bushing. Replacing your differentials rubber mounts with this kit will result in a snappier feel when cornering and better suspension performance. You save money by never having to replace the stock rubber mounts that fail due to old age and fatigue. These bushings are CNC machined in the USA and made with high-grade materials.

These solid differential bushings/mounts fit the following BMWs:

2014+ F22 BMW 228i 228iX M235i M235iX

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
Compatible with dual mount differential plates
Design:

Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:

Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: 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.

Modern BMW's are beginning to leave the performance derived handling and power delivery in the past as the demand for more comfort and features rises. The stiff suspension components designed around having the best driving experience from a luxury car has been left for the M models and replaced with soft rubber bushings and mounts. Unfortunately, this is a good move by BMW to support the masses.

The obvious approach was to offer products so the modern BMW can be upgraded into the car the enthusiast desires, superb handling, control, and a direct delivery of power to the rear wheels. When you upgrade to our Delrin subframe mounts you reconnect that power with almost zero negative feedback.

The added appeal to someone looking to take one of these machines on the race track is Delrin can be used when solid mounts are needed and aluminum is not an option with strict regulations found in??Grand-Am, BMW CCA, and other racing series.

Product features:

  • Precision machined Delrin(TM) 150 bushings.
  • Precision machined 6061-T6 aluminum inserts.?
  • Class legal for any racing class that does not allow a solid subframe bushing.?

Performance Benefits:

  • Eliminates subframe movement for more direct throttle and suspension? response.?
  • Minimizes wheel hop due to subframe deflection and movement.?

?

***Installation Instructions***

This package of OEM E82 E90 E92 diff mounts replaces the stock rubber diff bushings. On a tuned 335i you may have noticed more driveline shudder or problems hooking up during hard launches. What happens is the stock rubber bushings are under constant flex as engine torque is transmitted through the differential. Under normal driving with a stock car the bushings are rarely stressed. But factor in significant additional torque from a tuned N54/N55 and the stock rubber will quickly show its weaknesses. You may have even broken a diff bolt or two as the heavy differential shifts around. Even non-turbo E82 and E9X models may benefit from fresh bushings.

This is a set of stock rubber bushings, made by OEM supplier Lemforder. They are the same as the Genuine BMW E9X diff mount bushings, but without the more expensive branding. If you're turned off by potential side effects of urethane or Delrin then the OEM diff mounts are your best option. The OEM mounts fit and perform just like the originals so there is no second guessing their quality. If you're looking for an upgrade we offer E9X solid Delrin and aluminum diff mounts that work well, even in street applications.

E9X Diff Mount Set includes:

  • 33176760287 x 2, front differential mount
  • 33176770866 x 1, rear differential mount
  • (new hardware is optional and can be ordered separately below)

Single piece 6061 construction, optimized cooling, provisions for temp sensor, and external cooler with removable air duct.

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing the Turner diff cover can handle anything you throw at it. Not only is it an absolute masterpiece, but this billet diff cover checks all the boxes for features needed. Reinforced mounting ear for strength and stability. The mounting ear is unified with the one-piece billet cover and features added material for the highest durability possible. This diff cover is cool, literally, the entire construction was designed with optimized cooling in mind. External fins are strategically placed on the rear face, bottom, and between the mounting ears of the cover, serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication of the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable o-rings. The drain and fill plugs can now be used for an external oil cooler allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver seat is 1/8 NPT provision for temp sensors, this product from Turner has you covered at every turn.

Upgrading to our Turner Billet Differential cover gives you the strength you need to push your car to its limits without worrying about snapping a diff mount from clutch kicking or other shocks to the drivetrain. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, it also offers a visually appealing design.

Key Benefits:

Reinforced mounting ear for strength and stability 16% Increased fluid capacity External fins on the back side, bottom, and mounting ear on the casing for maximum cooling and consistent fluid temps Removeable air duct to direct air across the cooling fins for even more temperature control Optimized internal design to keep fluid consistently on the ring gear Integrated breather to prevent cavitation by venting the appropriate amount of pressure being built up in the diff housing -6AN ports to incorporate the use of a differential cooler - this increases capacity and lowers temps allowing for extended fluid change intervals 1/8 NPT fitting for the use of a temp sensor to monitor fluid temperature Design:
