Agree on the sticky suggestion and on the search engine.
Also search Ackerman effect on the web.
Based on a 981 and two 991s it's worse with P-Zeros than Michelin Pilot Super Sports and the 4s so far is more prone to this than was our 2s.

In all fairness, it comes down to our lousy search engine, again. I can't see how a new-ish Rennlister can find these nuances very easily or efficiently.
I encourage the wiser/more experienced guys to just find a good older post, and copy the link for the newer users, and just call it a day.

Welcome to the Board, Aman and enjoy your car.

I don't.
Google "Porsche 911 front tires skipping" and tell me what you see.
If you want to take it a step further (for the initiated) Google "Porsche 911 front tires skipping site:rennlist.com" .
To the mods: I do like the sticky idea (although many folks tend not to read stickys) using "front tires skipping when making slow, sharp turns...Ackerman Effect" (or something of that nature) ALONG WITH editing the title of the Acorn thread to better the search results. Acorn and Ackerman are words few will use when searching for information on the topic at hand.

It all comes down to the search words you use. I just typed in "Porsche 911 skid" and it doesn't come up with anything regarding the acorn effect. Give the guy some slack, it's really not that big of a deal.

As usual, new members are put off and discouraged. The consequences? Less traffic - less advertising clicks. Guess who the mods are going to punish? The new guys or the guys who can't control themselves from clicking on threads that they're not interested in and putting up useless posts.

According to Wiki, Ackermann discovered the outside wheels travel along a greater radius than the inside. So he then designed steering geometry to correct for this effect. Ackermann steering has been in use ever since. But why would you think this method of correcting that problem is causing this one?

It was a humbling experience for me to have the pretty young lady in the Porsche service department explain to me that it is perfectly normal for the wide tires on a 911 to skip in sharp slow speed turns in the parking lot.
