I previously had a base 350z (open differential) and swapped for the Nismo LSD

The 1.5 Nismo LSD definitely improved performance as far as off the line grip, corner entry and exit, maybe acceleration a bit, and for drifters it is a MUST HAVE.

For the everyday street drivers, I would not recommend this type of differential. The chattering and clunking noise is very very bad. Its loud and harsh. When making slow sharp turns, say in a parking lot for instance, the inside wheel would actually spudder and hop leaving rubber behind. I put only 7000 miles on a set of Goodyear F1 GSD3's. I believe mostly contributable to the differential.

I ended up swapping the open differential back into my base due to the very aggressive and nonpractical street nature of the Nismo LSD.

Conclusion:
Nismo, Quaife type LSD I would recommend only to those who track there car often, in which case you will love it

For a streetcar only, it is WAY too aggressive. stick with the viscuous lsd.

For the record: this is all IMHO
