Vibra Technics Performance Uprated Engine Mounts have been designed for high performance applications where a direct replacement for the standard mount is required along with a much higher level of engine control to cope with higher engine outputs, and higher road inputs caused by fast driving. The fast road mounts give significant improvements in ride and handling without adversely affecting vibration isolation. Strong enough for engine support during hard driving, but compliant enough for daily road use.Vibra Technics uprated engine mounts are manufactured primarily from natural rubber compounds and occasionally from blends of synthetic and natural rubber to give particular properties for specific applications. Extensive experience and testing in all kinds of environmental conditions by automobile manufacturers has shown that only natural rubber compounds give optimum performance and durability, which is why it is still universally used today by every car manufacturer.
