Vibra-Technics Left Hand Side Gearbox Mount For VW/Audi MQB

Engine mounting systems are a balance between isolating engine vibration and controlling engine movement. The engine mounting system is in effect an engine suspension system. Its geometry can be as critical as the main suspension system on your car. The same factors affect its performance, stiffness damping, deflection etc. When we design a system we go back to the first principals of vibration isolation, to ensure that we develop something which has the primary function of isolating vibration from your engine.

The main difference between a “Road” system and a “Competition” system is the point at which they isolate engine vibration. Road systems have to isolate vibration right down to idle speed which is extremely difficult to achieve whilst controlling engine movement and requires careful tuning of the mount stiffness. Be aware that the “Road” mounts are stiffer than the original equipment so may give some perceptible vibration. Competition systems have an isolation threshold above 3000RPM, below which the transmitted vibration can still be quite high. This allows us to make the system much stiffer to control engine movement to a minimum, typically less than 3mm (compared with 25-30mm for an OEM system).
