Look guys, I have on 03 z with 100k on it and I bought it with 85k on it and ever since I've got the car the diff just doesn't want to grab. It is just like having an open diff. Here are the things I do know, it's not a base model, I don't have traction control or cruise, and it's on 20x10.5 in the back with 255/35's on them.

So any help guys? Do I need to change the fluid or is this common with my mods and milage?

 

If you DONT have traction or cruise it IS a base. You have an open diff thats why it feels open lol.

 

Thanks for the clerification, now what's the easyest/cheapest upgrade or can I weld the spider gears?

 

theres numerous threads on different experiences with different lsds.

 

thanks but i cant seem to figure out the difference in the 3.3 or 3.9 or manual trans or auto trans. does it matter or just buy any vlsd for a good price? and is any better than others?

thanks

 

what are your goals/aspirations for the car?

1. looking for diff because i wanna burn out in front of chicks?

2. autoX, road race?

3. drift? - Nismo LSD - no messing around clunky, loud, gets the job done right kinda diff...

4. want lsd thats quiet and noise/clunk free? - search quaife

5. want lsd for safety in wet conditions, etc over open? - see 4

6. ???

7. ???

 

I think it really depends on the goals of your car and your style of driving, and preferences of service needs for the diff. There are numerous options for LSD's, the factory VLSD is fine for some, while others go with OS Giken or Quaife. There are also a couple of cheaper alternatives, but unfortunately I don't know anything about them and haven't heard anyone talking about them.

I wouldn't weld the spider gears together unless all you are using the car for is drag. Why are your rear tires so small? I'm assuming you just like the stretch look?

edit: good answer above by Jason.

 

is Quaife also good for drifting?

 

What would be the best route if it is driven everyday (sun or rain) but still want to do some sliding?

 

How well does a stock vlsd slide?

 

the stock diff is a paperweight
