Default handling question

I'm certainly familiar with the handling characteristics of the 911 related to the engine in the rear. Let off the gas, hot in a turn, and around you (could) go.

But at lower speeds, through turns, does one feel a little "kick" as well, when you let off the gas? Or, let off the power in a long sweeping turn and you have to adjust your steering a bit to counter the back end that lurches a little. Of course I'm doing a little comparison/contrast in my head with the '88 I had several years ago and I don't remember the "kick" being as pronounced. Suspension is stock for both.

Am I normal?

Probably. A stock torsion bar chassis 911 has a LOT of weight transfer, both on and off throttle. Especially pronounced in the lower gears (higher torque multiplication).

Bottom line, slow in and accelerate out. Or at least maintain a neutral throttle. Learn it, know it, live it (to quote Fast Times At Ridgemont High). So glad I was schooled in this at a young age.

"Hey man, just be glad I had fast reflexes!" - Jeff Spicoli

Getting on the track and some driving clinics definitely on the agenda. The nice thing about the 911 is it's a lot like my main mode, an R1200GS. Slow in, power through, and NEVER touch those brakes! Just LEAN, whoops, LEAN MORE!

PCA - PNWR offeres Drivers Skills in Bremerton for $65 - not sure how far of a drive that is for you...I have been to every one this year and almost every one the 2 year prior...they are a cheap way to learn ALOT!

You are (basically) normal.

What you are feeling are the changes in rear toe caused by lifting off the throttle and thusly, more toe-out as the car lifts. Its a characteristic of all semi-trailing arm suspension systems.

This can be controlled with shock valving and alignment settings to make the car less sensitive to small changes in throttle position and much more stable.
