Just picked my S up from the dealer today after a completed tsb-54. They actually changed the entire clutch assembly, flywheel and all that good stuff. Only question is that the clutch pedal is alot easier to push now, almost to easy, is that typical of a new clutch...oem by the way

 

I have yet to have TSB-54 done, but most say the new clutch is easier as well as stronger.
