Fluid comparison for Kaaz LSD
#11
Can I ask you guys why you went with the clutched diff over the stock unit? Sorry for such a basic question, but I was under the (perhaps false) impression that the stock Torsen was a pretty rugged unit.

Thanks Reverend... I've been wanting to switch to a different fluid for cost and availability reasons but I figure I'd use the Kaaz stuff until it has broken in all the way. I'll keep an eye on this thread to see how your Redline does.
Chazmo: I went w/ Kaaz because of stregth. Even though rare, I didn't want to take a chance w/ blowing the stock diff. I figured since I was cracking it open to replace the ring & pinion, I might as well change the diff as well. Most of what I've read on blown diffs were the bearing caps failing and/or ring & pinion failures. The Kaaz might be overkill for stregthening reasons. But I know others who get it rave about the Kaaz's performance on the track.

Thank you for the reply, futomame.
Final question from me: doesn't this break-in chatter business worry you guys?? It sounds to me like maybe the clutching isn't configured right. I don't know...
Anyway, best wishes!

I wouldn't call the stock Torsen rugged at all. I went with the Kaaz for durability as well. I found as a welcome side effect that it also improved the car's performance and made the car easier to drive.
The clutch noise is normal for a new LSD. Any time you have metal on metal grinding (which is basically how these diffs work), you're going to have imperfections that need to wear off before it acts normally and has normal friction levels.

OK, cool information.
Rev, I know I said I wouldn't ask any more questions (), but did you actually destroy your original Torsen diff? Your post casts some question about the stock diff, and I'm trying to get a feel for whether this thing really has durability issues or whether it's myth.

Without getting into too much detail, I didn't "destroy" it persay... but it became "glitchy." It would make loud clunking noises while turning at parking lot speeds.

I went through a guy named Dan Ponze from Godspeed racing. They have a website, but I dunno the url off-hand. It was about $800. But last time I talked to him, he said he also now sells ATS carbon lsd's. Supposedly they last a lot longer before needing the clutches replaced (basically the life of the car, I think). They're a little more expensive, but if you're going to go through the trouble of changing your diff, it's probably worth it.
