Default Why do I slip when i shift at higher rpm from 1st to 2nd gear?

Is it because I release the clutch too fast??

My friend told me this:
you release the clutch too fast making the wheels turn faster than the car's speed... meaning you jump the clutch and make the wheels spins without making the car fast... release the clutch slower will do the trick

Do you guys agree with this??

Today, a rainy day, I was waiting at the left turn light, when it turns green, i go and shift the gear at around 3k-3.5krpm, then my car slip, and it just lost control, luckily, i countersteer and saved the car...
Even in a dry day going straight, if i shift at higher gear, the car's slip light will turn on too.

What is my problem??
Thank you.

The Z is really sensitive from 1st to 2nd. Gotta wait a split second before releasing the clutch fully for daily driving.

your car slip at around 3k-3.5krpm? that's not called high rpm, that's a very normal rev for dairly driving. if it always slip you should practice more, or try release clutch little slower, then see what happen.

TCS is working just the way its supposed to. The rear tires are momentarily breaking traction. No big deal

sometimes i just want to drive with vdc OFF all the time...
but then my ZzzZzz driving is dangerous and i kind of have to put it ON
the VDC option comes in very very quickly more intrusive than DTM counter-parts ie BMW DSC

yeah it sounds like you're releasing the clutch too quickly. Don't just step off the pedal, you gotta work it a little.

You're either releasing the clutch to fast or giving to much power to early, or a combination of both.

It's learning time

Slipping is something entirely different than what you're referring to. Slipping is when a clutch doesn't hold or make a solid engagement. You step on the gas and the engine revs but the wheels don't turn even though the clutch is engaged. That is slipping and can indicate a worn clutch. Albeit you can slip a good clutch on purpose, although this is bad and speeds up clutch wear.

The rate at which you release the clutch has no bearing on making the wheels spin - so long as your rpm are in the right place. If you are overshooting a revmatch by 2k rpm and dump the clutch, depending on the gear and speed, your wheels will spin and/or your clutch is going to eat the extra power(not good). This known as a variation of powershifting.

I think you're taking your rpm too high for the type of driving you're doing. The Z makes plenty of torque down low and there is little reason to take it past 4k rpm unless you're intending on hauling ***. It's also easier for a novice to shift gears smoothly if you keep the rpm low.

1st to 2nd on a turn from a light in rain and it slips? Gee, that's just inconceivable. Slower clutch release and less gas and shift at lower RPM in rainy conditions like that; you just need to learn the car. The Z has enough power to spin the tires in a 1-2 or even 2-3 shift if you shift at high RPMs and drop the clutch.

Lift off the gas a little longer and don't get back on it so hard if it's forward slip. If it's backward (slowing) slip do the opposite. Like said befor practice.
