Could it still be air in the clutch line?

Would love to hear impressions on street driveability etc....

I was offered to drive the car but didnt. John @ Z1 got to drive them quite a bit. Im sure he has alot of feedback he could give.

It's kinda up in the air now. If Zerolift can get it soon, I will be running this clutch. If not, Competition Clutch will be the winner. Link below.

Mine has been at the shop being installed since last week :|
The shop must have gotten busy or something cause it has been a week and a day now. As soon as I get my car back I will share.

Awesome! Hope you get it back soon and post up your impressions!

The number 1 reason is "driveability" - the newly designed pressure plate allows for more room to machine holes in the pressure plate. This extra room and holes allow OS to install clips inside the plate.

Some benefits to the clips in the Pressure Plate are:
-Smoother engagement (standard TR & STR engagement is harsher than stock (some customers like this b/c of more aggressive engagement (on/off release of power), but some don't)
-Holds floater plate down, so when the clutch is disengaged, no annoying chattering when parallel parking or sitting at stop light
-Ability to pick pedal feel, hard or soft

The best reason to use this clutch set up is to maintain that OEM like engagement and pedal feel, even with 700HP!!

BTW this clutch is going to be installed into a daily driven NYC Twin Turbo 370Z...

I hope this GT clutch does come with a special heavy duty throwout bearing kit because I am not about to use the factory set up, which is plastic junk.

Please advice

Thanks

nope you are on your own for the hydraulics, be advised that you need to order the correct aftermarket replacement for an os twin plate.

Thanks for the advice. I will stick with Specialty Z street turbo clutch package. Much cheaper and no chatter. Only about 10% stiffer than factory, according to how I feel.

The reason I was considering the OS Giken was just to try a different clutch to see whether or not that helps on the pedal stiffness.... but the cost , in my opinion, is not worth it now that I might have to spend another $300 for another CSC assembly.

NO matter how good a clutch system is. You need to replace the CSC along with the master cylinder is what I"m getting from reading all these threads about clutches.

Yup the csc is gonna die no matter what, and if u change the flywheel i garuanty you will get chatter no matter what flywheel it is.

Oh yeah, the specialty Z street clutch does come with a custom billet CSC assembly. Factory CSC really sucks and up until now I still don't understand why Nissan or any manufacturers with their right mind would use plastic material on the CSC assembly.....
