I'm not sure how this thread got derailed to talk about the clutch helper spring, but the OP was asking about jerkiness from 1 to 2, which is unrelated to the helper spring issue (which to me, is all about better clutch feel in 1st when starting from a stop).

The jerkiness from 1-2 is because he's probably trying to shift fast at lower RPM. In order not to be jerky, you need to shift slower from 1-2 when your RPM are low ( <3K or so). Above 4K and you can shift as fast as you want with no jerkiness. Basically, drive slow -> shift slow, drive fast -> shift fast.

Actually feeling the clutch helps with shifts. 1-2 can be jerky if you are letting the clutch out too quickly.

What i don't get is... If your explanation is the solution to jerking sensation when shifting? Then this is the most pointless issue on the forum. Any car shifted at high RPM has torque jerk. Why is this being singled out on the Z??? Clutch feel is definitely more of a performance issue vs so called "jerky-shifting"

Jerk is a result of user error. If the combination of clutch and lever operation is not smooth, you will jerk. You basically become a jerker if you can't do it smooth. 1-2, jerkin' all the time.

Removal of the helper spring allows one to be smooth, which helps in preventing jerk.

Not saying you can't shift jerk free with the OEM spring, but it's much easier and more consistent without it.

So is it possible the user is a jerk? I mean...

Maybe it's just me, but I kinda like the jerky 1-2 feeling.

You must be a serial jerker.

Without proper clutch application you can jerk the car. But i didn't find the Z to have excessive jerkiness there. Just a very mild one. I jerk more when shifting from high up in the ranges over low 2500 rpm shifts.

It doesn't jerk excessively hard, per se, it's just much easier to jerk than other cars as a result of the crappy stock clutch operation.

Like, stock for stock, my 5.0 was way smoother. Much better clutch operation and therefore way harder to jerk. The Z, however, can be jerked so hard and so easily if you aren't uber careful with the stock helper spring. With it removed, however, it shifts like the Mustang. Smooth and harder to jerk.

Pulled or jerked should be the real question in this thread now...

It's also easier to modulate the clutch switching gears with the spring out. You can feel everything a little better.

More feel = better operation.

Barely-There makes it feel more natural.

Just jerk it.
