Well the first few miles on the clutch finally! It is a bit sticky, better than the stock clutch which only had 18500 miles on it.Only took 200 m. to toast it after installing the tt kit. the engagement is very quick, little drive ability right now. It may get a little smoother with some miles, pedal feel is about twice as stiff as the stock one. I would like to know some one else that has a aftermarket clutch to compare in person to see how they compare. And thanks Adam, the clutch alignment tool from other nissans did work.

I am surprised it is so stiff.....my single is lighter than my factory pedal. The pressure plate is only 1000kg, right? My engagement has softened noticeably since the install. Initially it would shutter if you left a light below 2k, but now it doesn't really do it (600 miles or so in).

good stuff Chris glad you got sorted on the alignment tool
the pressure plate clamp load on the aluminum cover, 215mm disk type is 1100kg. I have to search around and see what the stock HR pressure plate clamp load is - not sure if I've ever seen that info posted
you'll find that the engagement gets smoother and smoother as it's run in. Try doing around 400-500 miles on stop/go type driving, no launching, and avoiding solid speed cruising or full pull WOT runs. Once that's done, enjoy it!

Found the clamping force for the DE to be 1936 lb or about 878 KG. Found it here:

It may not be official, but I don't know otherwise. Wouldn't mind knowing for the HR also so I can compare with current aftermarket pressures.
EDIT: K, don't know why there's ** in the link supposed to be "350z- tech" where the ** are), but I just searched google "350z stock clamping force", 7-th link down.

So, if the clamping force is 1200 KG for the OSG Dual and the JWT clutch is 1200 KG, does the OSG have the same likelihood of causing the CSC to fail? I thought the pressure was lower in a dual.
The OSG would use the existing CSC right?
Excuse my ignorance on this stuff.

For some reason I think the stock one is near 800 kg. I'll see if I can find where, but I thought I read the JWT was 50% stiffer, it feels a lot stiffer so its possible.
Edit - 370z plate is 880kg, and has a nifty self adjusting mechanism that I don't remember seeing on my stock plate.

ok....... you are talking like the exedy wouldn't hold up to the osg or something. exedy is like the leading brand of clutches for imports. so you could still track the hell out of it and still get tons of hp out of it. i dont know maybe its just the way you made it sound was like you couldn't do those things with exedy clutch but you could with osg or something else.

Z1, true, stock is a consideration. Although, if I replace it, wouldn't mind upgrading since the trans would be out. Didn't think the stage 1 + flywheel was that serious of an upgrade. Stock flywheel and clutch can be a bit pricey, but if the CSC fails w/ an aftermarket clutch, it's hard to say which is the better route for cost. I'm thinking it might be worth taking a chance? I'm not looking to buy one soon, so I'll keep my eyes open here.
I'm more interested in seeing if any other clutches come out that tries to tackle the CSC issue. I'm hoping ATS and stock are not the only options.
