I have not gone for the NVH; I have been guided in this decision by the company's documented problems with rubber mounting other areas of the car!
e.g. Rectifier and exhausts
Also, in order to fit the kit parts have to be welded to the chassis and then the chassis re-painted/protected from rust. Seems a bit of a one way trip to me.
Hence i have adopted a policy of wait and see.
