Nevermind DOT 4 is acceptable and highly recommended over DOT 3 but NOT DOT 5 ok?

^^^^ how's you pedal feel ? I think I might have a little air in the system

Yeah you can feel the difference off the line with the new flywheel

As for fluid just splurge a little and just get RBF600

Im still in the process of breaking it in, and that could take a few months, I hardly drive my Z, but I did notice more pressure when I push the clutch in, did you see that as well? (Its kinda more effort to push the clutch in, basically)

Yeah I don't think it should be soft if you've upgraded. The stiffer the more pressure you have and the more effective the mechanism works. Maybe you should check your lines for loose screws just in case you're losing pressure somewhere? Food for thought.
