Aftermarket LSD's and you:
Anyone see the article in SCC this month comparing the Quaife, Nismo, stock, and open diffs for the G35?
I really liked what I read about the quaife unit, however, anyone have better insight on them or comparison experience? It appears the Quaife is a bit better suited for road racing than the nismo, but some of the data doesn't support that. However, the Nismo is said to be louder than the quaife.

Did they make comparisons for drag? I was considering the quaife because I have a base model and I heard its the only one that will bolt in with the base stub axles.

The Nismo LSD comes with the correct stub axles.

I don't get SCC and the article isn't online, can anybody scan it or give the gist of what it said? From what you've listed, its a comparison of the 4 predominant types of differentials; clutch, open, viscous and helical.
I've posted up my thoughts on them before, but if you have a direct question I can answer it. I had the VLSD, have the Quaife and have been in vehicles with the Nismo and open; so I'm pretty familiar with all 4 setups and the particular details between each one.

The Quaife unit is completely silent. It transitions from right-side to left-side bias instantaneously, seamlessly and smoothly. It's very strong; It has a lifetime, transferable warranty, even with racing and "unlimited" horse power applications. It requires no maintenance other than the normally scheduled differential fluid changes. If you completely lose traction to one rear tire (zero traction on that side), then zero torque is sent or "biased" to the other side. This could be a detriment in some situations, such as when/if a rear tire comes up off the ground in a hard corner. As long as both rear tires are touching the ground, you should be OK, except on snow and/or ice.

not sure if it's true though

especially when you do a slow turn. G

The real benifit, is the super smooth transition for unluck to 100% lock. You can barely feel it on the ATS Carbon.

it wasn't really a comparo as much as it was showing the differences in how different LSD systems work......clutch type vs. gear vs. viscous

what I got out of that article is
the nismo seems best for drifting
the quaife is smoother and a more linear engagement, so probably better for tracking
the stock VLSD is sorta ok, but slow to react to anything you do
the open diff kinda sucks, but if you know how to drive, you can make due with it and make it work out alright as far as lap times
What I primarily noticed when I added my LSD (nismo), is that going in a straight line is much more confident inspiring. The car hardly ever fishtails or at least not nearly as much. And also there seems to be more control when cornering. Throttle inputs actually seem like they do more or are more sensitive than before (compared to when I had the VLSD)

after upping the tires and rim size, making a turn from a stop I get wheel spin. (I have base, open Diff) I am getting a Nismo, so we will see if this is the fix I think.
and as Sentry said, straighline is hairy sometimes... not as stable as I would like.
