As the vehicles age and simple upgrades seeing the  2-ltr  turbo engine push power north of 250bhp, the OE rubber engine and transmission mounts are showing their age, with cracked rubber and excessive movement.  The effective rod design made from our Black 95A  material.  Designed to fit within the  voiding of the original mount, these new  inserts prolong the life of the OE mount by stiffening and limiting movement of the  rubber. This results in a more  settled transmission response during acceleration and deceleration, improving gear changes and reducing wheel-hop.  They  fill  the key voided areas of the mount to restrict engine roll, providing the perfect balance of compliance and rigidity, making them  ideally suited for your daily driven vehicle.
