Letting off the clutch?
 

Hey guys, I just bought a 370z sport touring 6 speed. I leave synchro rev off when I am normal driving. I have only 450 miles on the car and have had numerous passengers. I am not a complete stranger to stick, but this is my second week with the car. When I left off the clutch the car semi jerks 1st and 2nd And 3rd, but not in 4,5, and 6. If I release the clutch slowly, then I don't have that problem, but when I release quicker I do. Passengers say I release to slowly and I am burning the clutch. I say I am trying to avoid a jerk, they say I am burning the clutch letting it out slowly! Can I get some help please!!! Thank you!

Welcome to the world of Nissan clutches. Search for clutch issues or springs

Sounds like you guys need to practice.

Had the same issue and 3-4mos later I'm still feeling it out. I've been reading about removing or swapping out the helper spring and that makes a world of a difference. I'm about to search the DIY and try it.

:iagree:, I never understood why so many people have a hard time with the clutch on the Z... Yea it isn't the greatest in the world, but if you have experience with a manual transmission, you shouldn't have any problems... :confused:

Anyways, if OP is shifting with SRM off, and the car tends to jerk, then the RPMS are dropping to low in between shifts... so I would say a little more gas as you're letting off the clutch. Just practice, you'll get better.

Yep, it's the crappy OEM clutch spring. There was always something "off" that I couldn't fig out. I bought This new one off ebay and it made a world of difference. Easy to install.

Huge difference. Well worth the minimal time, effort, and cash.

Yup, or learn how to heal/toe it! :driving:

What does heel/toe have to do with upshifting?

Why would you turn off SyncroRev?

Synchro
 

I heard synchro rev is for racing only.

Yes, that is correct.

Remove clutch spring
Replace fluids (Nissan's is garbage)
????
Profit

Syncro Rev is there to make life simper and easier on the transmission as it avoids the potential for transmission snatch (not to be confused with other types of snatch btw) on up/down shift.

I have no idea of the logic that would lead to anyone turning it off given that it smooths both up and down-shift.

Getting the car off the line smoothly with the OEM clutch does call be a momentary clutch slip in my opinion, but it is just that, a momentary thing that requires some coordination and concentration.

I reckon you need to turn syncrorev back on and consciously practice getting underway with a minimal clutch slip until it becomes second nature. When I say momentary, I mean maybe a quarter second on so - enough for the vehicle to move a couple of feet and the road speed to match engine speed at maybe 14-1500 rpm.

:icon18: This... and now Porsche and the Vetts have auto rev matching. Heal toeing does the same thing, but takes some practice. Anyway, it's a benefit to you and you should use it (or not :icon14:)!

Why not just remove the spring all together? I bought one of the lightweight replacements from the GB, but ended up liking no spring at all.

Synchro Rev is insufficient for racing. Our data showed that it doesn't blip the throttle on downshifts nearly high enough. It's good for the street and the casual track-day guy, but once you get serious about it, it's best to turn it off and manage the revs yourself.

OP, turn SRM back on and pay attention to the relationship between gear, speed, and RPMs. Learn how the car wants to you to drive it. You should be able to smoothly shift fast (harder on the clutch) or slow (easy on the clutch). The Z doesn't like the in between stuff.

As for turning SRM off, many people enjoy rev matching themselves. I keep it on most of the time to keep down the wear on my clutch. But I will often turn it off when I do some "spirited" driving through the hill country.

I never turn mine off, nothing like switching to lower gears when entering a turn and blasting out of it on the apex. LOVE synchrev for that. I am not the best stick driver, but that button makes my life nice and easy

OP with the stock clutch spring in I had the same issue, had to slip the clutch for what seemed like too long. That said I never actually burned the clutch doing this..*shrug*

Pull out the clutch spring entirely, you'll be much happier :)
