Transmission Mounts
UUC Transmission Mount Options:
Option 1 - street cars and street cars that see track use:
Black neoprene BMW transmission mount bushings. These offer excellent drivetrain motion control Available with 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 we do expect some vibration transmitted into the cabin, initial user reports say that it is minimal and certainly acceptable.. Transmission mount enforcer cups not required.
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. Transmission mount enforcer cups not required.
