Major Track Faults of the 370

spearfish25

I'm highly suspicious of these reported clutch issues. Sure, some Zs have bad secondary cylinders that needed replacement, but that has largely been in Zs with aftermarket clutches installed. I can tell you that we just had 3 370Zs on track at Road America running 20-25min sessions and none of us had any clutch problems. Many of the turns require shifting down from 5th to 2nd and then winding it back out to 5th again in the subsequent straights. If we're not having clutch problems there, I can't imagine it's a fluid or mechanical issue (ie it's likely driver related).

You are assuming then that each and every CSC was built exactly the same to be in perfect working order. If we were so lucky on everything that nissan put into this car then no one woul dhave an issues period.

but then some people burn alot of oil
some people have sensor issues
some people have rattles
some have clutch issues
some have gear issues.

Its not a widespread 99% of people will have the problem.. I think Nissan's QC is good enough to prevent that from happening, but every company has issues with a small % of its things.

Think of anything that every went wrong on a car or product of yours. I guarantee you that you will be in the minority compared to people who didnt. Does that mean that you were the problem with it (whatever it was)?

Perhaps I didn't convey my opinion well in the first post. The clutch is a relatively fragile aspect of any manual transmission car that will readily be destroyed if improperly used. With the heresay available on this forum, the explanation of a defective CSC is just as likely as driver-induced destruction. Until people post videos of their clutching technique, it will remain a hazy area. I merely stated my suspicion that driver use/misuse may be a factor.

The OP is having a problem that many many other owners who track their Zs will never experience. I don't want people reading the OP's thread thinking that a clutch upgrade is a mandatory part of tracking the Z. It's not.

ahh yeah agree there.

Most of the time when someone posts something about "hey this happened to me, but i swear i wasnt doing anything wrong" or "I got a ticket but the cop was an *** I wasn't speeding etc" .. the OP is ussually bullshittin a bit. Not saying this OP is, but agreeing with your point spearfish..

Okay well how can I be shifting wrong? I have SRM on the whole time, so I doubt downshifting is the problem and I upshift perfectly with no jerking. What is the technique you guys are using that could be overheating my clutch?

I'm pretty sure it's a temperature problem that is causing it for a couple reasons. It progressively gets worse out on the track, and it goes back to normal after I let it sit for 30 mins or so. Is it was possible that there was air in my system or that the fluid is subpar?
