Default Car gets loose 7-9k in second
A few times I've had Rear wheels break loose in second gear under hard acceleration between 7-9K.

I've noticed a couple times now that the cars broken in that if I floor it 6K right around 8000 the back and gets loose and actually I see the traction control light flicker.

First car ever seen do this so high in the rpm range.

I know that's where all the power and torque is, interesting, anybody else experienced this? carl

Yes, the lower the gear the more it does it (really have to be careful in 1st gear), due to torque multiplication of the gearing. With 9k redline, the overall gearing is far lower than on a normal car (that's why 346 ft-lbs can do so much work)

Surprised me at first i thought it was something going on with the RWS?
Then i realized it was wheel spin.
My M2C will go side ways if you get on it in second but @3k and it has 405 FT lBs.
The GT3 surprised me because down low you really don't feel much torque and never have seen the back end getting louse mentioned in a road test....

You must’ve skipped the Chris Harris reviews

Tires and the road surface matter. Does it happen on all roads or just some?

If you watch The Straight Pipes videos of the 992 GT3 and Touring, and the 991 Speedster you can see how it happens at high revs on dry roads. They’re not so technical in their reviews but it’s a fun watch.

Is it cold out and no heat in the tires? In a straight line with warm tires and clean surface mine don't even break loose in first. Same experience across multiple 4.0L cars.

Mine doesn't break loose even in low speeds 20mph, Traction only flicker when I shift 1st to 2nd or 2nd to 3rd at 9k. (6MT btw)

Yes, extremely variable depending on tire temp, road surface, and steering angle.
