I have two possible flywheel options to sort out and thought that the list 
might help in that regard, especially those who are (have) running lighter 
components.  Have a lightened steel post 60k flywheel at 16#  and will be using 
a lightened ring gear at 2#,  Luk diaphragm pressure plate 10#,  McLeoud clutch 
disk at 3#,  and flywheel/PP attaching hardware at just under 1#  for a total 
weight behind the crank of 32#  with this combination.  The other option is a 
Fidanze AL flywheel at 11#,  and standard ring gear at 3#  with same ARP 
attaching hardware, PP and clutch disk for a total weight with this arrangement 
of 28#.   There isn't much weight difference (though if I used the lightened 
ring gear on the AL wheel it would make the total 27#)  between the two 
combinations, but I am told that reduction in rotating mass behind the flywheel 
can make a disportinant difference in take off.................obviously both 
conbinations are at least 15 to 20# lighter than the original TR2-3B setup.  
Thoughts, recomendations, comments, etc
Thanks,
Dan
