Question Flat shift and fishtailing in the GT3

Driving technique question from a noob here. This is in regards to my 992 GT3 Touring.

For background I've been driving manuals since I was a teenager (even took my driver's test in one) in various RWD cars; 93 RX7, 96 Silvia, and 2011 350z.

As I was driving my GT3 (manual) today, I flat-shifted into 2nd gear around 6-7000 RPM, and felt the backend fishtailing a bit. Luckily ESC was on as there were a few cars further back behind me and I maintained control of the vehicle, but still, it was a scary moment.

Road conditions were dry, car was warm, and stock tires still have about 40-50% tread left. Car was in Sport mode, with sport suspension enabled. Road was well paved and smooth.

I wonder if I was pressing the throttle too hard into the upshift? Could this be an issue with the car or is it just a technique problem? I'm thinking the latter, but hard to know what it was exactly. Makes me want to baby it when shifting into 2nd moving forward.

Appreciate your thoughts in advance. Thanks

A 500+ hp car fishtailed a little when you went full throttle in second gear? Im not surprised at all. Enjoy the car.

My thoughts are with over 500 HP @ 6k why would it not be trying to lose the back end. Be careful out there.

Not a technique issue, probably just a sign your tires are out of life. 40-50% tread that's likely.

It is a technique issue if the result is not as desired, the nannies kick in and it’s “a little scary.”

The torque multiplication of that much power in lower gears can yield this pretty much every time.

i would suggest training at the PEC, Skip Barber or private, proper skidpad training to equip you with the tools you will need as a driver to be more proactive, instead of reactive, when this occurs.

The dynamics and capabilities of the car are spectacular, But to be sure, it’s always easier to add speed than to take it off…

Cheers, and enjoy!

Just don't make the highlight reel of "supercars leaving cars & coffee". Respect the beast.

That’s an excellent feature newer 911s have that older 911s didn’t. Enjoy! You’re right to respect it as well.

I'll trade you my 944 for your car and I promise the problem will go away. For you, that is.

Find yourself an empty parking lot and "experiment" on what the car feels like with different inputs and at various attitudes.

Just be careful of the lightpoles.

OK dumb question... you can flat shift the new gt3,'s??

By flat shift I assume you mean no clutch/no lift?

Great advice. I think I'll be doing this once the weather improves at the local track. Cheers!
