I have the ACT streetlite Flywheel and Heavy duty clutch with stainless steel clutch line.

I personally think that is your best choice since you did say your going FI.
If you ever want to feel it before buying you know where I'm at.
There is some clutch chatter but its going to be like that with any aftermarket lighter flywheel.

 

There are many options available, including integrated jdm setups. I like my OS Giken STR--it's a twin clutch, the flywheel weighs about half of stock, the material is sintered bronze which is near indestructible, and the chatter is liveable, at least for me.

I would also check out the Ogura Clutch (ORC) 409 w/ all options (including "silence" which integrates spring dampers to resist harmonics associated with a lightweight flywheel in preventing chattering).

Other setups that many forum members have succes with is ACT, JWT, findanza, etc.
