I'm with prelude99 on this one. If you aren't experienced with the car sliding and it gets away from you on the street you just cut your losses and stick both feet in and get the car to a stop. If you don't know what you are doing you can easily make things way worse.

All the other advice here is good advice to be practiced in a controlled environment where you can afford to get it wrong.

Letting off the gas from a steady throttle will NOT allow the rear wheels to regain grip...it will do quite the opposite as dropping throttle always causes some degree of engine braking which causes less lateral traction to the rear tires because some of their traction is now being used to slow down. They teach you these concepts when you take the advanced motorcycle rider's course and the concept of traction applies to 2 or 4 wheeled vehicles.
The main reason you lose rear grip when you get off the throttle is that you're unloading the rear tires, greatly reducing their total tractive capacity.

Ill second that, for the extreme novice, but add one note.


When you go both feet in (Your intent is to totally STOP the car) Make sure the steering wheel is centered, or you could end up in multiple spins.


...and if you are going to try the proper car control method, as mentioned above

SMOOTH
SMOOTH
SMOOTH


that is the MOST important part of good car control.

Glad you are ok!

I still think that at high rpms, the engine braking on the rear wheels is a significant part of the grip loss.

If you lost grip from overthrottling, there wouldn't be any weight transfer if you abruptly went off-throttle... as you never had grip to weight transfer.

Agreed!

If you lost grip from too much throttle (really only possible in 1st gear in the S, unless you employ some novel driving techniques!), you will STILL have *some* acceleration even with wheelspin. Abruptly going to neutral throttle WILL unload the rear tires.

Acceleration with massive wheelspin is not insignificant, you do not lose *all* tractive force, probably not even half of it.

If you get throttle-induced oversteer and immediately stab the clutch (easiest reliable way I know of to get precisely zero engine accel/decel force at the wheels), you are likely to have the car come all the way around on you as it's already rotating and you just abruptly unloaded the rears at exactly the wrong instant.

Did you read the original post?

Frost + Blizzaks.

You can lose grip with part throttle in 6th gear. Especially on a ramp where uphill/downhill contributes. Trust me on this one.

Yeah, at those low low grip levels, the amount that you unload the rears is going to be negligible and the amount of engien drive/decel applied is going to dominate.

I was wondering what you were smoking...
