for N/A b15 sr20de.

cant find the part # or the weight of each, so pardon the stupid poll choices.

How about clutchmasters? 8lb. 12oz., it also has a replacable surface disk. I believe the Jun flywheel is chromoly, you can't resurface it. But the Jun is one piece vs. two piece Clutchmasters. I have the CM in my classic, works great.
