Stabilitrak also will apply opposite brake if slippage is detected if on.

well thats just wierd. it wasnt slippery at all. i have done it a few times just to prove to people it would do it and both times on different pavement with different conditions both tires broke loose. whats wierd is i have had many camaros with a posi rear end and my 2010 acts the same way as they did.

It's not posi, it's limited slip ... you can't run true posi on the street, you need to have the outside wheel turn faster than the inside when making a turn. With posi both wheels turn at the same rate of speed.

Sorry.. but that is not the case... Posi is short for Positraction which is simply Chevy's name for their Limited Slip Differential:

http://en.wikipedia.org/wiki/Limited_slip_differential

As Gentry78 mentioned it is possble to get both tires to spin but only when both tires have identical traction.... So if one tire is on a patch of ice and another is on nice dry pavement, then you just sit and spin the one tire on the ice...

Read my statement again, you confirmed my statement that it isn't posi but limited slip ....there is a big difference between posi and limited slip and I think GM know the difference. Posi is only used for going in a straight line and long sweeping curves, does not work for city driving ....

The V6 you can get with a Locking rear end but it is not standard .... With a locking rear end, if it is auto lock the computer will control it switching back and forth between posi and limited slip.

Also go look at the post with the V6 rental video..... Watch the part in the parking lot, if it were posi both wheels would be smoking at the same time .... The spinning is transferring back and forth depending on which way the turn is .....

You really don't have a clue... sorry... I don't have all day to try and educate you... Posi is GM's name for their Limited Slip Diff (LSD), just like Ford's is called Trac-Loc... From the link I gave you:

In the 1950s and 1960s many manufacturers began to apply brand names to their LSD units. While Packard pioneered the LSD under the brand name "Twin Traction" in 1956, the most famous of these was Chevrolet's "Positraction". Since then, Positraction (often shortened to "positrac" or merely "posi") has become a genericized trademark for LSDs.

The V6 auto is an simple open diff! It certainly is NOT a electronic contolled Locker! Posi = LSD!

BTW... I put plain old gear oil in my rear end... I did NOT add any friction modifier... if I had an LSD it would not like going aroud corners!

Also the rear end of a V6 auto is a different unit: (from http://www.popularmechanics.com/blog...s/4279655.html)

All Camaros use an 8.5-in. rear differential except the V6 automatic cars. They get a smaller, lighter unit.

Dont' believe me open the cover and take a picture for us...

Dude... You just don't get it.... There is a limited slip and a locker rear end .... Two basic types that are commonly used .... The locker comes in two types, Auto and Manual. The SS comes standard with the Auto Locker, cars such as NASCAR use manual lockers. Another example is with older 4x4's you had to get out and lock the hubs on the front end, those were manual lockers. The name posi was given by gearhead street racers on Woodward Avenue ......They came up with the name because it was the closest thing they had to a TRUE POSI rear end which is when both wheels turn at the same rate constantly .... You can call it what ever name you want, but technically it is still limited slip .....Just because you call it something doesn't make it so .... It's like comparing Kleenex Tissues and Puff tissues ... they are both actually tissues but a branded name of Kleenex is recognized as a tissue ....

you are correct but no one here is talking about loltrue 'positrac', they are just talking about options for the v6, so stay on topic.

I thought I had read that the 2LTs got LSD, is that not correct?

I don't have any idea where you got this info, but it is incorrect. For the V6, the manual comes with a LSD, the auto does not, and there is no other option available. Both the auto and the manual V8 come with an LSD, also with no upgrade option available.

I was a bit surprised to find the V6 auto does have a smaller rear end...

I seriously doubt it's a locking rear end... if you've ever driven one you would know that people would be complain.... it is most like an over sight on group that type up the web page..

also not it says MANUAL TRANSMISSION... no mention of automatic

Go take the cover off your V6 automatic so we can see what you are talking about....

as for the the webpage and that kind of info... was most likely outsourced to some foreign company....

BTW...the Woodward story was Classic! LOL
