JCivc has it wrong about the clutch type: the discs causes chatter when given load (this is the biggest complaintt on the KAAZ/Cusco/Mugen/Spoon units). The Torco friction additive helps much; many also do the break-in the worng way or not at all and then complain about the chatter. As for clutch disc life, it can actually outlive the motor's life span !!!
If someone rebuilds any of the clutch type units twice a year ??? it's because they're being over precautious it's not because they have to, IOW you have to be racing 50 weeks a year with an abuse drivetrain to have to rebuild, and still that rebuild will probably be 1.5 years later... As for the unit breaking, the gear type is more succeptable to break if one wheel comes off the ground then engages while the other wheel takes the load. I've done the same 2 wheel cornering with the KAAZ and it grabbed (almost lost control because I was oversteering ... my fault)... so I know I've done the rigorous testing of the KAAZ unit, I will not offer to do a test on the QUAIFFE unit, unless they offer me the free gearbox ... if anyone's ever seen where/how the QUAIFFE breaks, they'll know what I mean.
Not sure who said they know someone who knows someone who knows someone else whose neighbor had a diff that broke or whatever, but I've had both kinds of diffs, here is my point-of-view: The QUAIFFE i had was on my VWs, I went thru 2 QUAIFFE diffs, the second was a replacement from Autotech (not sure what they mean by "yet to see one break") the first was bought from a QUAIFFE English distributor.
I've had the KAAZ unit for over a period fo about 8 months now and I've never beaten on a diff this hard in my life. I've launched at full boost, done massive burnouts with my KAAZ and the thing still "dares" me to break it, wish I could say the same about the QUAIFFE in my VW tranny. I've also had th R diff (similar design less durability than QUAIFFE) and it couldn;t handle 300HP muchless 400+HP.
here is performance from QUAIFFE (VW; Honda must be similar) vs. KAAZ:
l/r wheel burnout:

=--=--=--=
I've driven a GSR turbo with the QUAIFFE and also did a burnout and found something similar: ===--====-- or something close to that (it wasn;t as dramatic as the VW but had the same alternating slip).
So these are the POVs from someone thats owned both http://www.hostboard.com/ubb/smile.gif
One other thing, I amd sponsored by KAAZ but in no way should it be assumed I'm biased since I also defend the Mugen/Spoon/Cusco/ATS and other clutch type diffs in the same regard.

So how long does the break in fluid have to stay in for the KAAZ unit??and does the fluid actually go into the diff itself or the tranny?? Thats alot of extra work if the diff has to be removed to change the fluid.

Ok, all of you that have LSD's.. what CV/axles are you running? I broke mine (6psi turbo) the other day and have to replace it now..
You say you BEAT on the LSD like crazy, well how does the axles take the abuse? have you upgraded? broken any? if so what are you using now?

I still use stock axles, I'm gettingt he KAAZ driveshafts for this upcoming seasons, but all last season I used the stock.
As for the abuse, the LSD reduces the single load stress on one side so it directly reduces the load of stress on the axles themselves since it tries to keep a balanced laod on both sides.
usually 4 (common) things breaks axles:
1) mis-aligned motor
2) bent chassis
3) big slicks/strong clutch/hard launch
4) too much wheel hop as driver holds down gas pedal.

How about
5. Hard cornering /w extreme lowering

nah, the fluid just goes in the tranny along with the lsd. you break it in with a procedure of running figure 8's for like 30min and then you put new fluid in and you are set to go.
