I am looking at the options and I want to know what the "Anti-Spin Rear Differential (DSA)" option is. Can someone please explain?

Thanks

 

I think thats the ESP function- this is when the rear wheels start to spin ie-snow/ice and it will automatically slow the wheel down to grip. If you drive in the snow and floor it, the wheels won't spin like crazy.

You cant do doughnuts in the snow unless you press the ESP off. Even then, the anti roll computer locks up the front brakes- no fun

 

Actually this is a LSD or Limited Slip Differential. It basically helps transfer power from a wheel that has lost traction (it's slipping) to one that has it.

To read all about them click here.

It's called Trac-Lok. If you get this with a 2-door (non-Rubi of course), it will upgrade your axle to a Dana 44.

 

The trac-lock is a mechanical action that puts more power to the wheel that is not spinning. The esp system provides an element of limited slip but does so with differential braking and uses a computer for its actuation. Both are good systems and I decided to get both but most of the time I will not need it. The tru-lock is as the name suggest. The back wheels are "locked and turn together".

 

IIRC all 6 spd. models have a Dana 44 regardless of any other options.

 

Good call - I didn't know that.

 

If it is a limited slip why don't they just call it that? I am after either an X with the 23S 4wd or possibly a Shahra 4wd. If it is the same as a limited slip I guess it is worth the 200 or so that it cost. Correct?

 

If you are ordering I would get it but if you find one with everything else you want and no LSD I'm not sure I'd wait for it. I would have preferred it but I found one on a lot without it so I picked it up figuring I could add it later since I like doing that sort of thing.

After looking into it a bit more I'm not sure I'm going to bother. The stock ESP does a great job of providing power to the rear wheels when there is slippage....it uses the brakes to slow down the slipping wheel and send more power to the one with traction (basically).
