I gave mine a go with the traction control off and it left two big black lines all the way through first gear. Seems awful close to a LSD to me.

 

I has a limited slip diff. Don't pay attention, it's a newbie thread with new owners who don't know what they're talking about...

 

Yeah your probably right, I will have to take a peak one of these days in the repair manual and actually see what's really going on in that differential.

On another note, I raced a Lincoln Mark 8 friday evening, you know the ones with the big duel overhead cam V8... I could let him get 2-3 car lengths on me (rolling at 50 mph). We both would just stomp on it, without any hesitation I easily run up on him, and pass that old grey hair, not today's grandpa!
Shoulda bought an SS Impala hehe.

Anyways, sorry for the thread jacking, just had to tell someone.

 

I remember taking a "thrill ride" at one of the Chrysler events in this area. The drivers were slinging the SRT6 and SRT8 all over the place and the turning points had serious amounts of tire rubber piled smeared across the surface.
They were all on the inside with much lighter marks from the outer tires.

Perhaps the diffs were either cooked or worn out from such activity?

I know my SRT will light 'em both up but it does act like a one legger from time to time. A decent rear suspension setup will plant the tires evenly but I doubt these things are set up for that. I haven't studied the dynamics of an IRS to see what kind of work would be needed to achieve the same result and how it would change the handling characteristics of the car. That's more up Derek's alley.
My 69 Road Runner would light both rears at will and even ****** the fronts 3-4 inches off the ground with an open rear end. The catch is that I had to build the rear suspension to plant the tires evenly. When I sold the car, I moved everything over to the hot rod. It worked well there too. I ended up trading that center section for a different unit with more streetable gears.
