Nissan's are built like legos.

They've been putting R200's in cars since at least '83.
R200 simply means the base casing/internal parts.
There's short-nose and long-nose cases.
There's options out there. I haven't seen the half-shafts out of the 370, so I'm not sure what will directly swap.

I got the base model 370Z and I have been reading your comments about the vsld on the Z, some comments make sense and others are just not helpful at all, so I went to read my manual that came with my 370Zs. This car comes equipped with ABLS(active brake limited slip) that acts like a LSD, this sistem applies brakes on the spinning wheel and transfer power to the other and works even when the VDC it's off. The VLSD does the same......Am I missing something here???????
Also the sport package does not give better performance than the base model, bigger tires and wheels are heavier and it's harder for the car to roll them, 0-60 and handling are not better. Please check racing cars, they don't use 19 inches, the brakes are better that I agree but the rest it's pure BS, the Sport package looks better with the wheels on but it's actually a slower car, the AUTOMATIC it's also faster, from my point of view this it's just marketing BS from NISSAN to get your extra $3k. If I want better performance I will get the Nismo and I don't care if does not give me better numbers 0-60 but I know that I will get better handling and cornering because of the suspension.

That is interesting. I was also wondering about the rear end on non-sport models. What you say sounds correct because for the the car to offer VDC then the differential cannot be open, doesn't make sense.

I also agree with you about the automatic transmission and the 19's. I think an MT is much more fun to drive but we are at the point where these ATs can outperform them. I think it was motor trend that tested a Z with AT that was faster at 0-60 & 1/4 mile.

Now I have a question...Would it be worth it to swap out the sport OE LSD for an aftermarket LSD product? Is there that big of a difference in performance with a Quaife vs stock sport?
I've had a Quaife installed in a past GTI and loved it so I do know their products are good!

Be definition, an open diff takes the path of least resistance...so if you're spinning one wheel, it'll spin that one harder and harder until the drive lets off.

No amount of "initially" will break both wheels loose.

All my RWD cars/trucks have had open diffs - this is the first one that has something of a locking diff - and when it comes to wheel spin, it's a different beast. Much easier to get sideways!

IDK, I have a non sport pkg and I can lay 2 stripes.

Bringing this back from the dead. But to answer you're question NO. The only way is to upgrade it with one of these on this thread
