HUTCHINSON Lower Engine Rubber Mount.
Connects and dampens the engine to the lower subframe.
The engine in your MINI can shake and vibrate under torque and driving. These mounts were designed to prevent these vibrations from being transmitted, but over time, they can wear down. Typically, the rubber wears out and can crack and if this occurs, you will notice noises, exhaust leaks, clunking, lurching, or possibly even damaged hoses and belts.
Its good to replace main bolts: Hexagon screw with flange(M12X1,5X90) ES14505 x 1 & Hex bolt (M12X1,5X60) ES14504 x 1 as they both rust.
