Tight turn tire dancing...
I know this is considered "normal behavior", but has anyone else noticed it getting MUCH worse with the advent of colder temps or is it just me? My wife says "You need to get that fixed! It's embarrassing."
Actually, she's right. In a small restaurant parking lot tonight, with a few peeps standing around watching "the new Vette" leaving, it skittered and jumped like crazy...much more than ever before in my 2800 miles.
What gives?
Also, could someone with a good command of the English language explain exactly what's going on? I've never owned a car that did this.

It is the result of the Ackerman steering angle geometry being adjusted to favor high speed driving at the expense of slow speed turning. Cold temperatures affect the grip of the tires, and make it more noticeable. So yes it does get worse at colder temps.
For a good explanation of "Ackerman steering" do a Google search of the term. I highly recommend you at least read Wikipedia's article first.
It is normal for a high performance handling automobile. Most of us have never driven automobiles that were engineered for ultimate handling, and were never exposed to this behavior.
You don't need a mastery of the English language, but experience in automotive handling dynamics.

Does the C6 do this as well? I never noticed this. I don't think this kind of steering behavior is suitable for any car sold to be driven as a daily driver.

Scraping the splitter.
Since you apparently have one, shouldn't you already know the answer to this question?
BTW...weren't you previously banned? You avatar picture is the same as one posted by a previous member who frequently bragged about also owning an SSR (lmao). He also bragged about being in the motion picture business, and told people that he could get them Bowling Green tours.

No...that's you. I remember that house in the background.
You used to be TorchedC6 or something like that. You ended up getting banned. You also had pics of an SSR and started a thread that you could get people tours of BG because you knew people there and let them on movie sets.

The laws of physics dictate that it occurs because of the Ackerman angle and width of tires. It doesn't happen other than very slow, very tight turning maneuver commonly encountered only in parking the car.

Yep. He had another picture of an SSR in the driveway too with a different camera angle.
This was the same person who claimed they could get people in for BG tours because he returned the favor by letting them tour movie (or TV) studios where he works. He took a lot of flack in that thread and it was eventually locked.

I don't have this issue on either of my C6s. Sounds like an engineering defect to me. Unacceptable for any street car.

Its actually insufficient ackermann to be exact, and i cant for the life of me understand why the c5-7 is under ackermanned. It hurts performance badly at all realistic cornering speeds, and the tighter the turn the more it demolishes front end grip. Unless it was a packaging issue, the only reason for it would be to induce understeer by reducing front grip- worst of all worlds.

Check my post #2.
Reverse Ackerman angle is used to counteract the affects of differing slip angles of the front tires during high speed cornering.
If you want to brag about your cars low lap time, and high Gs' on the skid pad, that some magazine reported, then this is what helped achieve those high numbers.
Just part of the cost of bragging rights even if you will never take advantage of the cars capabilities.
