Anyone running Quaife LSD?
 

Hello,

I have a base Z with an open diff. and I want a LSD for both daily and track. I'm also on budget.....meaning I can't afford 2k+ LSD. Z1 is selling Quaife LSD for around 1k and installation is far more quicker/easier than others. It doesn't require any other parts for installation.

If anyone is running Quaife LSD or is knowledgeable about Quaife, please feel free to share your thoughts.

Also, I know that Quaife is Helical Automatic Torque Bias LSD. On the other hand, there is clutch type LSD like OS Giken. What are the benefits/disadvantages when running HATB LSD compared to clutch type?

And how the hell do you pronounce Quaife?

I love mine. Huge improvement over my OEM VLSD

Kwayf, if that makes sense. Lol.

I have a Quaife with OEM 6MT gears and a KAAZ 2-way with 4:08:1 gears.

The Quaife is quite soft in operation and works well enough on the track until I start being aggressive with the kerbs. Once one rear wheel is airborne over the kerbs, the Quaife is like an open diff, you need both rear tyres on the tarmac for it to lock.

Check auto wikipedia for details on operation of ATB and plate-types - it is relatively simple conceptually.

The KAAZ is one mean mutha .... it is set to be very aggressive and is worth as much as a second/lap for me at some tracks, and next to no time at others - it depends on the nature of each circuit and whether lap-time comes from being smooth and flowing the car, or whether the lap-time comes from being aggressive over kerbs and that is where the KAAZ shines because mine is very close to fully locked

Around town, the KAAZ is a PITA - it clanks, groans and creaks and puts a huge stress onto the drive-shaft CV joints, whereas the Quaife is a pussy-cat (in the absence of torque, it is effectively open, it is the application of torque in the driveline with differing wheel speeds that causes the helical gears in the diff to put pressure into the diff and force drive equally to both driveshafts).

Given your budget objectives, the Quaife is the way to go ... for outright performance, a 2-way will be the better option.

If the car will be daily driven go with the Quaife. I have one in mine and love the feel on the street. As said above, it will act as an open diff if a rear wheel loses contact with the ground. Luckily I've only had that happen a few times during autox events.

^ That about sums it up with everyone. I love mine, but remember the install will set you back another $1k with labor and supporting parts. Mine was installed at the dealer for $800 ish but look at the sticky thread on what else you will need.

Also it does not require special oil and you can rip on it right after the install, no break in period or procedure required.

i just picked up a wavetrac versus a quaife because i was concerned with warrantying the quaife and the whole one wheel in the air = no traction issue. ive heard warranty is a bitch since they're a UK company and you'd have to deal with your vendor. the wavetrac improves on the quaife in that if one wheel is in the air, the other wheel still has traction. cant wait to install it!!

What do you mean by supporting parts? I have to purchase something other than the Quaife differential itself? Or do you simply mean Diff. oil, seal, etc.

seals, bearings, axle stubs, diff cover (suggested).

i'm installing my wavetrac this weekend, and i've got quite a few supporting parts ready:

• an entire rebuild kit (seals, all new bearings, etc) - $200
• driver side axle stub - $150
• nismo diff cover - $130
• 2 quarts of motul 300 75w90 - $40
• new washers - $2

if you dont have a new diff bushing installed already, that would be another $100 for a whiteline bushing

I was under the impression that the Quaife was the only thing you need, no axle stubs or anything like that?

Zdayz 2015 woohoo!

That's what I've been hearing

We had to cut the stub axle on mine. I have the QDF13L model.

I wish I would have known about the wavetrac when I did the Quaife, but I can say that I have no regrets with the Quaife. if it ever fails I'll go the Wavetech route, but on the street you won't know the difference & I figure the only time I need wheel in the air traction is times like this

This is going into my car later this year for the same reasons, did you buy direct from wavetrac or thru nissan motorsports usa?

woops, forgot. yea, you wont need any axle stubs with a quaife. they have specific models for base or VLSD replacement. you'll still need the other stuff though. bushing is definitely recommended as the stock one WILL fail. guaranteed. replace it while you have the diff out.

well the quaife loses traction in 2 circumstances, when one tire is in the air, and when you go from accel > decel. the wavetrac solves both of these issues. i got my wavetrac from todd at vividracing. he hooked it up, and they are a legit distributor!
