Not getting too much info in the first gen section.

I need some info on what I should put in my road race car.

Looking at Torsen options, KAAZ, and OS Giken units.

Any input is appreciated as I need to make a decision within a week!

Any one with any opinions on the Quaife vs. the OS Giken differentials?

There was a test in Grassroots motorsports on limited slip diffs a few months back. The car was a Miata, and the favorite was an OS Giken as it had smoother lock in the high speed sections. I don't think a quaife was used in the test, but most people seem to prefer the Giken.

Almost correct. The car was an S2000 and it was stock vs. KAAZ vs. OS Giken. and the Giken won.

I was looking for first-hand feedback if possible. Here is the article:

I also noticed that I mis-linked my own discussion on the subject:

Trying to make a decision by early next week!
