Just installed a Sachs 764PP with 997GT3RS 4.0 clutch disc and a 964RS LWFW. I really like the combo and have about 300 miles on it now. Clutch take up is perfect and buttery smooth. When the engine is at idle, there is absolutely zero noise when the gearbox oil is cold/warm and just a touch of light chatter when the gear oil is hot. The chatter is only audible in the car with the radio off. Outside the car you really can't hear it. I think the 997GT3RS 4.0 clutch disc is a winner. It has smaller springs which are rumored to make it quieter than the traditional 996GT3RS disc (w/ blue springs) and maybe more durable since Porsche puts it in the 997GT2RS also. So far a winner all around...

 

..GREAT..
Does sound like the hot ticket then, Thanks
