I still think the Quaife LSD is the best mod I have ever done to my Z.

Here is some "cut and paste" from other threads I have posted in regarding the Quaife....

I have done many auto-cross events with my quaife and have noticed that having the outside tire get most of the power in a turn helps the car rotate through turns. (kind of like mild 4-wheel steering?)

I have never driven a clutch-type LSD but I can't imagine another LSD being any smoother.

I can't remember the exact numbers but, IIRC, the Quaife shaved well over a second off of our 40 sec "test & tune" course. The helical design is really a big plus for turns. Having the outside rear tire get most of the power in a turn is almost like four wheel steering. It actually helps the car turn, when you learn to use the throttle with it.

Worth every penny!

"...Well the wife and I just got back from the Tail of the Dragon, (ZdayZ) and I had a chance to A/B the Quaife vs. the stock LSD and I can say the Quaife is noticeably better. Both the guy I swapped cars with and myself noticed the difference immidiately. The quaife actualy helps the car through the turns. The stock LSD allways seemed a hair "late" hooking up and seemed to be making an "approximate" attempt at traction.The Quaife was always ready and seemed to be waiting on the driver to apply throttle in every turn.
I'm guessing the time it takes for the different wheel speeds to lock the stock LSD gives it that "late" feeling and, when it locked up in a turn, it seemed to do so after the inside tire was already spinning a little too fast, thus giving a little wheelspin from both tires when it kicked in.

This, of course, is all relative to the Quaife. I still remember how frustrating it was to try and power out of corners with my open diff and the stock LSD does a much better job than the open diff, just not as good as the Quaife.

BTW: ...the guy I swapped with [road racer], said he is getting the Quaife ASAP......"
