Rear Diff: Base vs OEM VLSD

Pariz

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.
