I have the jwt flywheel on my g35. I love the responsiveness, but the noise drives me nuts(and I have full exhaust, headers, test pipes, catback), and it completely killed my torque off idle. This is a mod I would not do again.
I only have a butt-dyno to go on at this point, but suspect your experience doesn't apply here... I don't feel a torque drop at low end... dyno will tell the full story

Listening to my car supports this statement... press in clutch, very little rattle... release clutch (in neutral), lots of rattle
