This mount fits all Corrados, MKIIs and MKIIIs and replaces the notoriously leaky, fluid filled mounts on most applications. Our mounts are made using all OEM brackets to ensure a perfect fit and simplify installation. The STG 3 mount is significantly harder than the Polyurethane STG 1 version and is intended for all out performance at a great sacrifice in ride comfort. The transmission mount can generate an a fair amount of vibration, which is why almost every MKII and MKIII came with a hydro version. However they are not durable and allow a lot of engine movement.
