Just saw the post I put up in 2002!! Nearly 10 years ago.. I'm going to correct what I said all those years ago, some clutches do rattle from the get go, the current car has a new HKS twin plate in it and its quite rattly with the clutch in.
And bugger with the throw out bearing, its quite possible the clutch is well on the way out too as the clutch and bearing are usually replaced at the same time.
