Does anyone have the oem diff weight with the VLSD with or without oil?

I think I may have taken a pic when we tossed the oem on the scale. Let me look thorugh the albums

Sorry, was the wavetrac unit we weighed.

Last page I posted that filled with fluid a manual vlsd with oil is 87lbs.

Hey guys yes I did see that. So a question about that, are the wavetrac and quaife units about the same weight? I don't really need the whole assembly weight although I'm looking to see what the oem weight is for comparison. Even with just the lsd themselves then I can see roughly how much heavier the wavetrac lsd is over the oem VLSD.

Who cares? The best money spent on a 370z is to upgrade the diff. Who cares about how much it weighs? Some folks just way over think things.

Not everyone pursues the same aspects or qualities in their build. I respect that it wouldn't make a difference to another individual but I am asking for reasons that are important to me. I am upgrading the diff to a wavetrac unit and was looking to see the secondary benefit of how much weight would be added to rear to offset the weight of an SC up front. There was an entire mega thread where people discussed weight reduction, distribution, etc. because it was of interest to them so there are definitely people out there who care. Perhaps you have something else to contribute other than frustration? :tiphat:

I can't tell you the weight of the diff but when my car was supercharged with an OS Giken diff, I had my car corner balanced and the front weight was 2025 and rear was 1684 for a 54.5% front and 45.5% rear. That was with driver weight of 195#.

It's because any weight difference will be negligible due to the added performance of the corner exit speed you will gain with the diff. The best option is an OS Giken but you will need to add a diff cooler for it to keep it from overheating and puking diff fluid out the vent tube. When and if you get an upgraded diff installed you will see what I am talking about. It is the best money you can spend on a 370z to improve track times. As far as my frustrations, Sounds like you need a date with AOC. LMAO!!!!

Thanks for the input, you definitely have quite the heavy car. I think I would only need about 20lbs in the rear to stay at the same factory F/R distribution which I believe the difference is between diffs.

I have considered many options but after researching all my options I decided the wavetrac was what I was looking for as I was looking for something streetable and quiet.

OS Giken is streetable and quiet as long as you use the OS Giken diff fluid.

You haven't really stated what your actual goal is, other than to keep the balance of the car the same as OEM. It that is the case then just stick with the factory diff if you aren't doing any performance driving. The Z is not bad from the factory but it is not great.

^^^^This. My OS Giken doesn't make any noise

A little bit over 3500 pounds without driver. The supercharger set up is heavy.

Mine is dead quite.

The weight difference between different LSD units is ounces. Maybe a pound at the most.
