I currently have the Fidanza flywheel and not sure if I will exchange it for the SZ segmented flywheel and either the SZ Hi 5 or Max Street. Also have heard good things about the Southbend clutches. Looks like you have a good setup already so I will watch to see what you end up doing. But at the moment I plan on the SZ Hi5 and flywheel. I have the Z1 one piece drive shaft and so far I like it. Also I have the Stillen short shifter and it tends to be a little sensitive to position (notchie, if that's a word) and not forgiving during aggressive shifting. Since I have my engine and tranny out I have considered the Z1 short throw as I have heard good things about them but I am sure there are other good manufacturers as well. Good luck
