Anyone have any experience with a Sachs K70350-01 clutch replacement kit for a 2004 A4 3.0 6-speed? I need to replace my original clutch after 90K miles. The pressure plate is starting to vibrate through the clutch pedal when pressed to the floor. Other recommendations appreciated. I own a 2004 A4 Quattro 3.0 Ultrasport 6-speed.
