So, Jon, as you know, I just had mine installed out of necessity (let's call it that lol). Today, the day after, I was hearing a...i dunno, grinding kind of sound, almost like the synchros were grinding, but there was no mechanical movement or shuddering to the car...My clutch and flywheel are OEM, about 60k on it total. Rob told me that the clutch looked good..

What do you think it could be? Do I need to let my car come up to normal operating temperatures before trying to engage the clutch..?

I've heard from a friend that the more you have (aftermarket wise) the smaller window of adjustment you have...currently, he's got a Nismo 350 with the latest RJM adjustable clutch pedal, aftermarket master cylinder, clutch, flywheel, and the Z1 elimination kit. With those, he's saying he has to periodically adjust (more than average) due to the stack height and wear on the clutch.

So the more you have done, the more you're going to have to adjust it. Personally, I still have oem flywheel and clutch, so I haven't had a need to adjust just yet. 8k miles and still running strong.

Ummmm.... no. I've installed many aftermarket clutches and components over the years and if everything is done right, like John said, there is only one time you have to adjust anything. After that, it's just :driving: If your friend is having to readjust things on a regular basis, then one of two things is going on, he didn't get the adjustment nuts locked tight or there is a problem in the install. :twocents:

Thinking about what you guys have said, I'm thinking he probably installed the parts post-z1 elimination kit install.

In other news, someone else I know has had their Zspeed HD CSC fail....+1 for the the z1 elim. group.
