dont all specs hav lsd

how od you know if you have lsd? is it in the stikcer thingy?

If you don't track the car or drive in snow you might never notice the difference.

All specs have LSD. That was one of Nissan's selling points.

I see on Nissanusa.com that it is a $400 option, money well spent.

Yep it sure is an option. When I was shopping around for Specs most of the ones I saw did not have it. I finally found 1 fully loaded Spec not far from my home that had it.

Thats retarded

I thought someone in here actually had the lsd installed in there spec after buying it.Im curious why they would have to buy a whole new tranny.

Only an idiot wouldn't notice.  I used to drive a car that didn't have an LSD.  I can definately tell the difference.  I am an aggressive driver though.

It is a $400 option, as far as I was informed by Nissan when I sold their vehicles was that it must also have the Summer Tires option. Most common is finding the vehicle completely loaded roof, fosgate system, with Summer Tires and LSD or bare bones without summer tires and LSD.

B15 SpecV's had LSD's I believe SE-R's were open differentials, even the 5 Speed SE-R's... Though it may have been an option on the SE-R, not 100% sure, I know I have never seen it.

I think you would need to have two of the same car with and without to really tell if there's a differences in everyday driving. I mean an LSD equipped spec v vs say a Camry isn't exactly going to tell you much.

The LSD is there to try and get the max grip out of the tires under hard driving conditions. When you start to spin them the tires stop doing their job and start becoming like hockey pucks on ice. So as far as I know unless you have spun your tires on a non LSD car and doing the same thing and not spinning your tires in an LSD car you haven't really push it hard enough to really tell what it means.

it wasnt on my sticker and i have it equal wheel spin on both tires

same here i dont have a lsd and both of my wheels spin??

to figure out whether or not you have a lsd. just jack up both front wheels. spin one side. if the other spins in the opposite direction you don't have it.

Does that actually work? Cause apparently with most geared LSDs you need both wheels loaded for it to work as an LSD. Apparently, that means it doesn't always helps that much on snow and ice. If one wheel completely loses grip it can stop working and just spin that wheel.

Shouldn't there be a way to find out whether or not your car has the LSD by reading the VIN?

I'm a proud new owner of an '07 Super Black Spec V - RF, moonroof, mud guards, and door moldings. I bought this car used with 5000 miles on it, so I can't be certain if mine is LSD equipped. Based off of what everyone is posting in here, mine should have it considering the option packages it is equipped with. Any help would be great!

Look underneathe the car.  Is helical limited-slip differential written on the differential?

Wow, is it really that easy? If so, I'm whipping out the hydro jack...

Yeah, it's that easy.  It should be written with a multi-color graffiti style font (for added awesome).

Of course, I'm going to assume you know that I'm not serious.

In all seriousness, you can whip out the hydro jack.  As someone stated earlier, when you have the front end up, give one of the wheels a spin and watch to see what the other wheel does.

Ok, I've heard this LSD spin one wheel test and whats the other do a few different ways. If it spins the other direction it IS an LSD. If you spin one tire and the other does nothing, it is an OPEN differential. Think of the purpose of the limited slip, if one of the wheels spins it is supposed to lock and spin the other wheel for optimum traction. If you put it on a rack and spin one wheel and the other does nothing, then even if you have an LSD it's not doing anything.

Viscous LSD's are most popular in RWD car's. Viscous LSD's typically have smoother engagement and make less noise. Helical LSD's are most common on FWD's. In fact I've never heard of a VLSD in a FWD car, I believe this is because the limited space for the gears as well as the perks of a helical LSD. Helical LSD's use the forces created by wheel spin to transfer power to outside wheel when cornering. Instead of truelly locking helical LSD's put the power to the wheel which is not spinning and continues to switch back and forth as that changes. The purpose of this is that equal power distribution on a FWD while cornering would light up the inside tire and be less effective. It transfers the power to the wheel with he weight on it and the best traction. Pushing the car into the corner.

I don't have the LSD but the option in Canada for 07' was only available with the "sport package" for a extra $1500 and I cant have a sun roof. Im to tall and my head rubs. So I didnt have that option otherwise I would have taken it :-)

But ya..I find you only really notice it in hi speed turns...and Winter driving...Big difference!!

Im sure they will be replaceing my tranny soon. Im wondering If when they decide to do that if I can pay the 400.00 to get the LSD .. Im ganna ask on Tuesday when I take the stupid car in.
