I pushed the Z within my limits. Hard shifts and lots of redlining

My CSC was actually still functioning when I replaced it 20K miles later (at ~50K miles). I sent it to fountainhead - he cut it open and put some pics in the engine/drivetrain tech section I'm pretty sure.

sounds good. thought you mentioned you had clutch pedal return issue, was that just from hot fluid or something or..? wat caused that, do you think?

Wait, FPenvy's Z is auto? I don't think I've ever seen a thread where he has mentioned that....

Not quite sure what you're trying to say here. By "lifting" do you mean letting the pedal come back up on it's own when you push it past the high engagement point? If so, what's the difference between that and having to push the clutch pedal further before engaging the clutch with a lower engagement point? Also, you don't have to push the clutch pedal passed the point of disengagement. A lower engagement point just equals more pedal travel. I'm not sure how it could possibly improve "feel" as you suggest.

With the exception of professional drivers, I can't imagine your foot travel is any different during hard (racing) shifts between a high engagement point and a low engagement point. You're pretty much going to be stomping on the clutch as hard and quickly as possible (all the way to the floor) and then letting off quickly and completely. I have a really low engagement but it is also super short. In a racing application I would adjust the upper switch, too, so that it stops the pedal barely above the engagement range. That way, as soon as I touch the pedal, it is manipulating the clutch. This allows the lower engagement point without the extra pedal travel.

It was the CMC. That's why it was kinda sorta funky for a few days before I figured it out. If it had been the CSC, I would have lost the pedal entirely.

i'm in line with how you like it. when i depress the clutch, i instinctively want to have it down to the floor. a low engagement point makes it easier for dd since there's less pivoting of the foot. just raise ur foot up an inch or so n it engages. i have some friends that prefer a high engagement point n their foot is basically hovering when engaging/disengaging. i tried it n it is the weirdest sh1t to me.

So you are not a long time MT driver I take it? Some years of MT operation should develop your leg strength and muscle memory so that "hovering" your foot while operating the clutch becomes second nature.

I've only been driving stick for 4 years, but knowing myself, I wouldn't have it any other way in terms of clutch engagement. I know exactly where my clutch engages, I just want it to engage low is all. My style is to pivot my foot off the floor.

I assume just the Z in those 4 years. Pivoting off the floor is fine if it works for you. I do it occasionally when I'm feeling lazy. But it doesn't work in all vehicles, so being able to adapt is key.

Keep on

Yep. 99% of it on the z. I've driven a number of my friends' manual cars and also for one of my past jobs. A few of them had high engagement so pivoting didn't always work.
