What clutch are the turbo people running?

RCZ

The OSGiken clutch is one of the hardest on the CSC. It will blow your stock one quickly so just go with the upgraded one right away...

My Z isn't boosted but the stock clutch has taken plenty of abuse launching. ~100 track launches and half of them were @4,000 rpm. (knock on wood)

When I had it taken out it was still usable (no slipping), I put in a new OEM clutch for good measure (installed lightweight flywheel). no complaints from me on the stock clutch.

Are you running the stock CSC or an upgraded one?

Also running the os giken but had the csc replaced to prevent any issues. How are you guys launching with this clutch it grabs hard and stutters if i dont treat the stop light like a xmas tree, I feel like a 16 yr old learning how to shift a manual again :/

Just got my own OS Gkien Grant Touring Twin Disc... anxiously waiting to get some time to put it in with our own custom CSC.

350z 370z heavy duty CSC Concentic clutch slave cylinder

just specify the os giken as its more expensive

RCZ

why is there a osg specific version??

Joe@ZSpeed

I won't go into much detail about this as obviously from the post in here others are making there own CSC versions.

There are areas that need addressed just for the OS giken clutches, get this wrong and the slave will not last long at all if it makes out of the garage before it blows out.

Over the last 2 years of testing with many different clutch set-ups we have all the bugs worked out and have an amazing product!

We have many, many customers in our Zspeed HD CSC with Zero failures. We actually have one customer that has been through 2 OS giken twin disk rebuilds on the same slave kit, he does nothing but drifting and beats the living **** out of it Says a lot for its durability.

Joe@ZSpeed

Just click the drop down menu and choose OS giken

I already have a Csc in my car from you guys. I was just curious as to why the osg one is different. I got a feeling it has to do with how stiff the osg clutches are to disengage...btw, I know of one of your units failing on an osg clutch on a 370z in Miami. Don't need to be more specific. I have no idea if he had the osg specific one or not, but he got a new one and it's been fine since!

Joe@ZSpeed

Not because it is stiff but for other reasons.

Yes we did have one in FL that had failed, He had the wrong slave style for the OS Giken and is why it failed, This was due to a fitment issue, not that it just failed.

RCZ

Ok, good to know the whole story there. I thought it was weird. I wont keep asking too many questions either! Thanks for coming out with it, great product. I have recommended it many times.

So, my stock clutch isn't up to the task after all. Time to look at some options.

Anyone using the South Bend TZR with the kevlar disc?

I am looking at that with the billet steel flywheel.

I want a streetable clutch that will still take a beating.
