My car had this clutch and flywheel when I purchased it and it chattered a bit. I personally dont like 6puck clutches for a daily driver. It can be a PITA in traffic. It has such a grabby nature. When i inspected it after around 15k miles of use from previous owner the disc was worn very uneven to the point of being minimum thickness to the rivets in some areas while plenty of life left in other areas. I had the flywheel balanced while rebuilding the motor and it took a good bit of dimples drilled in it to get it balanced. I chose not to re-install it and bought a southbend clutch from zspeed performance. Heres a thread on the other forum about this clutch.Ive dropped my tranny 3 times and believe me when i say if you can do it right the first time and keep from doing it any time soon,thats what you want to do. If i was you I would wait until you have the money for a better clutch or borrow the money to get one. [ http://www.300zxclub.com/showthread.php?t=121782&highlight=xtd ]
