They come with a 3.08 from the factory. Some guys will swap it out for a 3.55 since it is a real nice mod.

Sorry, can't answer that question.
exactly i know my old e36 m3 at a 25% LSD while the newer e46 M3 has a 100% LSD. I'm just curious to see what the Vipers have.

Just wondering but would a 100% LSD be the same as a locked differential or positrac?
Positrac is what one of my other fiends said the viper had but I just did a google search and it said positrac is the just GM term for LSD. It makes no mention of what % of power is transferred to the non-spinning wheel.

It's impossible to spin just one rear wheel on a Viper. Does that answer your question?

the funniest thing is that you have a pic of it in your avatar
It is ironic, but I have never heard anyone use the acronym "lsd". Well not with cars anyway!
A) Posi - yes
B) limited slip - yes
C) trac-lok - yes
D) locker - yes
and if someone's going to mention it, I realize that "A" and "C" are brand variances of the category "B". "D" being a locking type non clutch, watch the @ss end of your car come around the corner as you accelerate. Most people seem to use all of the above interchangeably when referring to a rear end with a non "open differential". Anyway learn something new everyday.
No i know that the system always send a certain amount of power to the other non-spinning wheel but my question is what % of power.
I guess we're on two different ends of the spectrum. I've always been more into european cars (viper really has been the only exception) and LSD is a very common term, funny I'd never heard of positrac until recently.

Mine came with Pink Floyd and Led Zeppelin too.
Both great with lsd.

Someone who knows what they are talking about please correct me, but the Viper has a friction clutch type positraction unit which when the car is driving straight and both rear wheels are turning at the same rate mimics a locked differential (like the spool units drag racers use) but allows the wheels to turn at different rate when turning a corner by allowing its clutch to slip (which I believe requires differing torque to be applied to the individual axles by the tipres rotating at different speeds - which is not present when you are spinning the tires). By definition I believe this means torque is split 50/50. This is unlike a torsen (I believe Quaife units are torsen technology) which has a mechanical ability to put more than 50% of the torque to a non-spinning wheel and when turning corners has a smoother action than a clutch type posi unit. And unlike a electronically controlled locking differential like that used on the Subaru STi, Mitsubishi Evolution and Ferrari 430. I hope I am thinking correctly.
it's not a locker, I'm pretty sure of that - I just bought a new house with a sorta steep-ish drive way, hitting it at an angle means one of the rear's is off the ground, car goes no where.
just did this 30 mins ago, going to have a wee look in teh service manual to see what it reckons.
Oh, and I actually searched for LSD, I'm australian and its a very common term (for us, but then again I reckon the car has a bonnet and a boot, not this hood and trunk rubbish)
