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

For our Grand-Am Cup E46 M3s we wanted a fully solid differential mount setup. The advantages of a fully-solid aluminum set is that they last forever, quickens response in the suspension, and frees up horsepower to the wheels. These fully solid aluminum diff mounts are CNC machined and lightened for a direct replacement of the original rubber pieces.

By substituting aluminum for rubber we can take out all of the deflection and 'wind up' inherent to the original rubber pieces. The high deflection rate of the stock rubber means the suspension reacts slower as the bushing is compressed. The power used to compress that bushing is instead passed straight to the axles and wheels. And since there is no time lost to deflection, response is greatly improved. These diff mounts are only recommended for racecars since the aluminum transfers more noise and vibration.

This is a 3-piece set with a single front bushing and two rear bushings to press into the cover. They mount with the stock BMW hardware.

This item fits the following BMWs:
2001-2006 E46 BMW M3

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.?

?

BMW does not sell the differential mounts separate from the cover. And as with all rubber mounts, they will have to be replaced at some point, forcing you to also buy a new diff cover. This is an Original BMW part.
**Note** - a paper gasket is not sold with this cover. BMW no longer uses paper gaskets - they advise the use of a silicone sealant such as RTV black.

Applications:
2001-2006 E46 M3, M3 CSL, coupe and convertible
