Wanted: cusco, ralliart or kaaz LSD preferably 1.5 way but will think about a 1way if somebody has a 1way to suit a standard hg vr4 box

Item Information: looking for a 2nd hand one or if anyone knows any places where I can get new LSD's for under $1500 please let me know. But I doubt it cause I haven't been able to find new one for any less than $1700.

Location: Adelaide

Contact Details: PM

Terms: pick up if item is in Adelaide or postage if interstate

Ask Joey (boost lover) I fitted a Quaif in his Auto
Dunno what he paid new
Cheers !

There was a Japanese seller on EBay who has been trying to sell front and rear Cusco LSD's for ages. Looks like the front one has been sold now unfortunately??, but the rear is still up for sale.
Here was the auction for the front LSD: http://cgi.ebay.com....=item5192a72d8a . You could try messaging him and ask if he has anymore. I bought my Ralliart front LSD from him a few months ago and it took 7 weeks to get to me lol...

[xtract]

Haha you wouldn't believe it but that was me who bought the front LSD from that jap ebay seller. I was stoked, paid $140 for postage so it would arrive in 3-6 days and I made the payment straight away and the seller sent me a msg saying he can't find the LSD, but can I wait a day so he can have a look for it because he said he doesn't remember selling it. So I waited and a day later which was yesterday he replied and told me he has given me a full refund because he can't find it any where, what a bloody front loop! So that's why I'm searching for another one now. Not happy!

[Jonson]

Why post something for sale if you don't even have it?! Dodgy ebay carnts.

I purchased a kaaz LSD last year and all prices just went up.

I paid about 1.5k for it then.


What about a viscous LSD?
There are some for sale.

[xtract]

Was thinking about viscous and then started reading about them and didn't really like them. Really want a plate LSD.

[ENGINR]

Why don't you like viscous LSDs? Will you really be able to tell the difference between the two?

[xtract]

Don't know, just came to the conclusion that viscous aren't as good as clutch type.
I been reading the viscous fluid gets hot and deterioates too quickly and then you loose your differential action.
If you can convince me other wise I may get a viscous lsd if I can't find any clutch type.. What's a new and 2nd hand viscous LSD worth?

It's not upto me to convince you which way to go, I just reckon people have this thing in their heads that a) a front LSD is a MUST have and that a viscous LSD is no good without any real understanding or experience.

99% of these people would a) have no idea that a front LSD will make a track car more unpredictable to drive and handle than a track car without a front LSD and would not be able to tell the difference and benefit from having a mech LSD over a viscous LSD.

[xtract]

Yeh good points mate.
Well I do think a front LSD in my FWD car with a 63t is a MUST otherwise the one front wheel won't stop spinning through 1st, 2nd and 3rd and I don't need to worry about the car being unpredictable on the track because I'm not racing it on track. I just want an LSD to help minimise the front wheel spinning as much as possible when accelerating hard and to reduce torque steer.
Maybe all I need is a viscous LSD, I don't know but just from what I've read I have liked the sound of a plate type over a viscous lsd. I have heard viscous aren't as reliable, I'm still new to all this and learning more each day so any advice given from you more experienced guys is all taken on board.
I just want which ever LSD i get to last as long as possible and if the viscous is going to last 100,000km no worries without the fluid thinning due to excessive heat over time then I guess the viscous will be the one for me. But if it wont then I would rather spend a little more money on the clutch type that will last longer and be stronger.

[Rockabilly]

I have run a viscous lsd with a locked auto fwd..It is a bit hit & miss in being
a consistant lsd bite..But it does feel good because the car pulls out of the
corner a lot quicker than a hollow diff fwd..A clutch front lsd would be more
consistant..I have no idea about the newer 1:5 ratio clutch lsds out there.
Maybe people who use them can jump in & tell us how they react/bite.
Cheers !

[ENGINR]

I smell a Tech Sticky!! To front LSD or not to front LSD and which to LSD with - viscous or mech!?

[Evo-00x]

Read this then make up your own mind
http://en.wikipedia....ip_differential

Choosing the right front LSD, viscous or mechanical is up to you. Remember, a 1-way front LSD will still work the same as an open diff when off the throttle - something you would find yourself doing a lot of in a FWD when understeering around a corner. Then when you're ready to put the power down it'll instantly engage and you're on your way.

[Rockabilly]

XTRACT another thing you need to consider if you choose a Viscous LSD
The inner hole dia is roughly 10mm larger. < Can't fit a std crown wheel.
The bolt holes pcd is larger than a hollow or mech lsd hemisphere.
Bolts are 5mm longer with a viscous lsd. Hollow or clutch are identical.
A crown wheel from a hollow or mech lsd both fit a clutch lsd. < Handy.
The top left pic is a viscous lsd crown wheel for a manual Evo 2 box.
I had to match the dimentions for my auto crown wheel. $800 labour.



I will have an Evo 2 front viscous crown wheel spare from buying George's LSD.
If you choose viscous lsd & want it, you can have it for $100.
**If your box is not an Evo 2, then you need to definately go clutch lsd
otherwise your up for the machining of whatever crown wheel you use.
**But rear hollow & viscous lsd & clutch lsd use identical crown wheels

A viscous lsd will outlast a clutch lsd many times over. That's why factories fitted them as stock items and only fitted clutch lsd's to competition versions. Clutch lsd's require more frequent oil changes and regular maintenenance as the clutch plates everntually wear down and you lose the "limited slip" benefit.

A clutch lsd is basically a locked diff, until enough differential force forces it to slip.

For a street driven front wheel drive, I'd look into a Quaife helical lsd. All the benefits of an open diff (driveability) with all the benefits of a clutch lsd and nil maintenance (apart from normal oil changes).

XTRACT another thing you need to consider if you choose a Viscous LSD

you also need to consider when fitting the viscous lsd is that not only will you have to change the ratio but you will also need to machine out the inside of the gearbox housing to take the larger diametre crown wheel, unless you have an RS gearbox housing

That's another reason why I am leaning towards a clutch lsd, I have heard a few people say a viscous is a bit hit & miss in being a consistant lsd bite and it's not as smooth.

I know nothing about quaife helical lsd so I think I might have a read up on that type of lsd, maybe it is the way to go. A lot to think about by the looks of it, still would be happy with a cusco 1 or 1.5 way though since I haven't read anything bad about them,

Mike Dale is the man that I'm buying the rebuilt vr4 box from, he has it all ready for me, just need to find the LSD for it. That's 2 people now that have said he is Adelaide's VR4 gearbox specialist

Just read the quaife website and they seem to be very good, I'm liking the sound of them. Let me guess they are very expensive? Can they fit into a vr4 box?

The Quaife I put into Joey's auto can't run the speedo, but his isn't a clutch lsd.
Your VR4 crown wheel should bolt to a clutch lsd..Won't bolt to a viscous lsd.
If you had an Evo 2 box, I could help out with a crown wheel for a viscous lsd.
A viscous lsd & a modded VR4 crown will cost you 12 to 1300.
A serviced 2nd hand clutch lsd will be about the same.
A new clutch lsd will be the dearest option.
Nothing is cheap these days.
