Have used A1 clutches in Tipton a couple of times in the last few years. Firstly, for a replacement clutch for my sons Corsa and more recently a clutch for my car. On both occasions I found them to be efficient, friendly and helpful. What is more they charged half of what I was quoted by the main dealer. They supplied me with a courtesy car and have a schedule of after care service where they make checks at various interval ie 500 miles , 3000 miles, 6000 miles etc. We had a slight issue with the clutch on my sons car and they dealt with it straight away, no waiting, no hassle.
What more would you want? Would have no qualms about using them again.
