I’ve noticed that bigger wheels with shorter-sidewall tires tend to break traction quite easily, as compared to smaller wheels with larger sidewalls.

Since you’re driving mainly in 2nd and 3rd gear, it makes sense to me that you’re getting slight oversteer. The torque magnification from the lower gears make it easier to slip the rear wheels.

I’m not sure how an LSD actually behaves on our cars (I have an open diff), but I’ve heard that it does help promote oversteer.

...but he's mentioned understeer in his opening post.

Sorry, I hijacked. Bad forum etiquette. OP, enjoy your car!

My vote is on the setup. Mine had understeer when I bought it through to when I changed to coilovers and the different alignment specs. So, wheels from 17" to 18", Height drop of around 1.5", camber change from 0 to -1.5.(X74 spec) For the street it's quite good. I just got done with a rally which really challenged my abilities, but the car never understeered. Good luck, a million things to try!

Reading this thread (and others like it) and many of the replies leads me to believe some track time with an instructor or some skidpad sessions would be very helpful. Fast road driving just isn't (or at least it shouldn't be) the same. There is a lot of knowledge on this site and the contributors for the most part are awesome with sharing and explaining their knowledge, but nothing beats first hand experience, good tutelage, and proper practice.

I almost binned my 996 on the first canyon drive thinking it would rotate, but instead the front just washed out on trail brake. Alignment and tires alone made a night-and-day difference, a more modified example could do anything.

Ehhh fast road driving eventually just becomes tarmac rally if you're irresponsible enough. And the first rule of tarmac rally is brake to steer, which is pretty universal whether you're thrashing a 996 or a tank of an Audi S6.

Guys I am with you.

If I was emperor of the world for a week, I would put every high performance car owner thru a mandatory 2 day training starting with autocross school and then track school to educate them on vehicle dynamics and how to drive. But the consequence would be far less entertaining YouTube videos of guys crashing their cars when leaving cars and coffee on cold tires.

I have been a PCA instructor for years, and there is nothing better than when a student has an 'Aha" moment sometime during the day as it all starts to come together. It's usually when you get them strapped in to the passenger seat and you take them for a ride at speed later in the day. They then realize the importance of tires, grip, brakes, suspension set-up, smooth driver inputs and transitions, all of which are ingredients in balancing the car around the track to carry more speed. All of which translates into safer street driving.

There is my pitch. If you own a 996, sign up for a track day to understand vehicle dynamics and become a more effective driver. You will be suprised with what your 996 can actually do.
