I have the Xtreme Twin Plate Clutch installed in my Z. Rated at 885 lb-ft.
It can be a challenge to take off quickly in 1st gear in a smooth manner due to the sudden on/off clutch engagement feel (or lack thereof) of the standard pedal. I'll have the RJM AFP Clutch Pedal System installed later this summer. Hopefully that helps to provide for a smoother 1st gear engagement from a full stop.

edit: plus, it's kinda noisy in different ways. this is my first-ever aftermarket race clutch, so it's new to me that a clutch can be making so many weird noises - but quite normal I'm told.
