Limited Slip Differentials

Hey, Guys. I am looking into getting an 06 or 07 GT. Do the 05/06 GT's come with an option to add Limited Slip Differentails to them? I seen a couple of people talking about it. Also, can anyone give me a better understanding of what they do? I kind of have a vague understanding.

GT comes stock with traction control. It controls wheel slippage by rapidly applying & releasing brake pressure (many times/second) when a wheel loses traction. Not quite the same as the old limited slip rear end or posi-traction but it works ok.

I decided to get the T-Lok differential for the Dix after a day at the drag, where I found out about what it's like to do a one-wheel burnout! All of the power from the engine was being directed to the right rear wheel. The diff redistributes the horsies to both rear wheels, resulting in firmer/safer launches. It's standard on the GT as per STL's post...and I think a must for anyone who wants to whip their Pony off the line every now and then...

Thumbs up

From my understanding with the GT stock traction control does not allow one to do burnouts, is this true? I just want to make sure If I decide to do a burnout, that both wheels will spin. And were you guys saying that LSD comes stock on the GT or were you refering to the traction control option? Thanks for the replies.

I 'thought' all GT's had a limited slip stock.

Re: Limited Slip Differentials

Just to clarify things...Limited Slip is not to be confused with Traction Control, but people often do confuse them.

As stated earlier by zregime, Traction Control is standard on all of the new Mustangs. The Limited Slip is standard on the GTs and available as an option on the V6 cars in a package.

Even though it is standard and alway on when you start the car, Traction Control can and, IMO, SHOULD, be turned off all of the time (unless you are a 16 year old girl!). Ford's version cuts power to regain traction. Not good for drag launches or attempting a burn out.

Limited Slip allows both wheels to try for traction at the same time and stil allows for differential turning radiuses of the wheels on both sides of the car during turns. IMO, all cars that could see winter conditions should have a limited slip and here is why...

With an open rear, the wheel with the least traction will spin wildly while the other wheel just sits there gathering dust (or snow). You could be stopped with one wheel in a slick spot and be stuck not able to move. With a Limited Slip rear, both wheels will turn and eventually, at least one wheel will grab something, allowing you to pull away. The only benefit to an open rear is a little less parasitic drag on smooth dry pavement.

OK, I'll step down from my soap box now.

Re: Limited Slip Differentials

How come the 2006 Ford Mustang brochure states that the limited slip diff is optional on the GT automatic trans cars, but it is really standard equipment?

It's also cheaper, has no clutches to wear, and has less violent break-away when excessive power does cause a break of traction.

I prefer a limited slip too, but an open diff generally feels much more "benign" when pushed past the limit.
