Thank you for your feedback. There is one customer I am aware of who has been very vocal in his dissatisfaction (which I think you are referring to). He blew off the clutch's disc liners. Despite being definitely not a clutch failure, and rather a mis-shift problem, and being out of warranty, we offered to cover the cost of parts. He wanted a new clutch instead - which we were unable to do. Clutches are a hard item to sell, because their function and durability depends so much on proper installation and driving. Regardless of the cause, it is always the parts problem however.
These clutches are one of our top selling items, and with several hundred in the field our customers we have many satisfied customers. By using the high quality components - pressure plates (made by the same company in Japan that makes the factory units) and discs, etc. we're able to offer a clutch that we stand behind (and use in our own cars).
cheers,
