UUC Motorwerks USA!
Black urethane transmission mount bushings. These offer excellent drivetrain motion control Available with or without transmission mount enforcer cups (combination of bushings and enforcer cups strongly recommended for E36 M3).
This part is intended for race/track cars and combination street/track cars.
UUC Motorwerks own description:
GENERATION 2 now shipping!
New mechanical retention system on all UUC isolated transmission mounts (red or black) and engine mounts. This design uses a bonded end plate plus an inner plate embedded in the urethane. This inner plate prevents separation of the mount assembly even under excessive force.
What's a Transmission Mount?
The transmission mount is an integral part of the drivetrain support which isolates the cabin from powertrain vibration and noise when you drive your car. To understand the technicalities of the transmission mount, there are a few items that should covered.
Vibration Absorber
First and foremost, the purpose of a transmission mount is to isolate vibration from the interior cabin. Without it, your interior cabin noise will increase to the point where it would be uncomfortable to drive any significant amount of time.
Deflection Fighter
The transmission mount is also used to combat transmission/powertrain movement during driving. Since the transmission is connected to the back of the engine, it is the engine which is doing the twisting when one accelerates or decelerates (engine braking). Since the engine has it's own mounts, the transmission also has it's own. Whereas some movement is expected, too much movement will cause the transmission to become misaligned with the interior of the car. When the transmission is not in the same position, it may lead "mis-shifting" (shifting into the incorrect gear). Generally, a mis-shift causes an engine to over-rev and cause extensive internal damage. Especially in an E36 M3, it generally means a few thousand dollars in repairs (and that's why they call it the "money shift"!).
The Ideal Mount
The ideal transmission mount will both absorb vibration as the factory intended as well as minimize the amount of transmission movement during spirited driving. By firming up the transmission mounts, your gear shifts will become more precise than when you car was new from the factory.
Our bushings even incorporate the small notch required for certain models including E46 330i/Ci 6-speed.
Hundreds of drivers from daily driven cars to full blown race cars have gained the benefit of the TME with near elimination transmission movement. Speedvision teams such as TC Kline, Turner Motorsport, and ERT to name a few, have all benefited from the TME. Are you next?

Option 1 - street cars and street cars that see track use:
Black urethane transmission mount bushings. These offer excellent drivetrain motion control Available with or without transmission mount enforcer cups (combination of bushings and enforcer cups strongly recommended for E36 M3).
Option 2 - street cars that see heavy track use, dedicated track cars:
Red urethane isolated transmission mount bushings, which are replacing our previous-style red neoprene. These are fully isolated, having two seperate mounting bolt hardware pieces embedded in the material just like the black neoprene and OE BMW bushings. The urethane is a higher durometer (stiffer) material than the neoprene and offers nearly the same drivetrain motion control as a solid delrin or aluminum mount, but with significant vibration isolation. That last detail makes it a better choice for a track car that is occassionally street-driven, where cabin noise is a concern. While UUC does expect some vibration transmitted into the cabin, initial user reports say that it is minimal and certainly acceptable.
Option 3 - dedicated track, road race, and drag race cars only:
Red urethane bolt-through transmission mount bushings are the strongest choice. A single bolt through the entire piece eliminates any possibility of bushing material failure even under the most abusive conditions. Offers effectively the same drivetrain motion control as a solid delrin or aluminum mount, but with some vibration isolation to reduce vibratory stress on mechanical components. Cabin vibration significantly lower than delrin/aluminum solid mounts, but still noticeable.
