Transmission Mount - Racing version

To meet the demanding needs of racers, the new TM-R features a hybrid design sharing features of our standard TME bushings and solid metal racing mounts:

• High-durometer urethane bushings are stiff enough to provide nearly flex-free support, yet still absorb some amount of vibration.
  
• Continuous bolt-through design eliminates flex and bushing separation from rotational forces (especially with high-powered cars).
  
• Reduces torque and power loss from rubber mounting flex.
  
• Direct-fit design with correct clearance notch ensures hassle-free installation on any 1992-2005 3-series or M3.
  
• Stainless steel hardware.
  
• UUC transmission mount enforcers are not required.

How is this different from the standard UUC Transmission Mount?

standard street-style bushing is two separate bolts within material.

The standard BMW bushings and the standard UUC bushings do not have a continuous bolt.  Despite appearances, those bushings actually have two separate threaded rods within the bushing material.  While this is an ideal design for a street car, a race car has different requirements.  Noise and vibration isolation are not race car priorities and are happily swapped in favor of a stiffer and stronger design.

The TM-R meets these requirements with a stiff urethane and strong single bolt that will not allow the bushing to pull apart or break, regardless of how much powertrain torque is applied.
