...you know.... there's a whole post on what's required. *cough

I love mine but I haven't come to the point were I don't want all 4 wheels on the ground.

Can't comment on the Quaife or standard Kaaz, but the Kaaz Super-Q is great, very easy to live with, and it works with the stock stubs.

Looks to me that op has done his homework for the most part and was just asking for personal experience and or to fill in something he might have missed.... You know..... And I believe there's more than just a post on it. Maybe even a thread or two. :tiphat: cough.

I am doing a TT build soon, might have to go with a quaife over the VLSD.

Love my Quaife & 7A/T with 3.357 gearing will still light up 345's.https://uploads.tapatalk-cdn.com/201...4b4c62deb7.jpghttps://uploads.tapatalk-cdn.com/201...455ccde074.jpg

The wavetrace seems like the way to go if or when I become unhappy with the vlsd but sadly no AT option. So weird nissan made two diffs for the z. Oops maybe I'm wrong and the wavetrace can work with AT diff as well, vivid site specifies it for 6mt but z1 only specifies vlsd or open.

OS Giken 1.5 way.

I've been running the Quaife for the past two years. The biggest issue I have with it is getting in driveways. Sometimes coming in at an angle will cause the rear ending to lift on one side - especially with aftermarket sway bars - and I can't accelerate. I have to plan ahead a bit on the driveway at my home with a bit of momentum otherwise the car will spin the wheel in the air and will go nowhere. When both wheels are on the road, it's been a solid unit. No problems in 20k miles and I can feel it working its magic in tight corners. Also makes for good empty parking lot fun.

Anyone running Quaife LSD?
 

Quaif stays very cool and it is much lower maintenance then a clutch style. You probably can skip a diff cooler at track days. (I do).

True that it looses grip when lifting a rear wheel (and on ice and snow) but I love mine at the track.

It also torque vectors so it kind of "pushes" you around turns helping with understeer on the exit or corners

It is a good/ great option for a weekend warrior in fact I argue unless you a fully dedicated track car than it's the best choice (at least it was for me)

Z1 knows what stuff you need to install based on your base setup.

Be careful if you install a new stub axle that it has the same number of cogs in the ABS sensor "cog". My replacement from Z1 had a different cog and it was a bitch to figure out what was causing the intermittent Xmas tree of dash lights from the computer trying to make sense of the discrepancy!!! (The cog tells the computer how fast your wheel is turning).

BTW. Due to the expertise needed to getting the gear lash correct using a ton of different spacers this is not a DIY install. Perhaps have your shop order from Z1 if you are unsure about what supporting seals and parts etc you need.

This would be a good time to swap up to an aluminum finned (NISMO style)diff cover which will help keep your diff a bit cooler.

I have Wavetrac which is basically the same as Quaif but it does lock so there is still power going to the wheel that is in the air or slipping!

I am going with OS Giken. Heard nothing but good reviews and my mechanic also agrees and he works on tons of Z's. But he wants me to get suspension first so it will handle the change better. Just my two cents

I did my suspension first and after I had my rear diff installed I realized it was way more valuable and noticeable than some of my suspension parts. If you like track days it will allow you to put the power down more efficiently, get in an out of corners faster and be more predictable when you loose traction. Adding suspension to this will only make all things better. Get the diff you want regret it!

I have an OS Giken coming.
