If you did find something as good and for less, I am of course very open to that as my budget is spent and now I am having to work towards my lsd goals for autox.


Oh where does he say that? That picture and his text only says the front, maybe I missed something....?

If that price included both front and centre, that would be a good price.

Once we have our project sorted, we will be looking for interested parties...

Are you sure about that?
(Especially in regard to the ATB/torsen style of diff we're discussing)


Yes, 100% sure, fro example, a friend of mine runs a Suzuki Swift Sport, has a close ratio transmission and Quaife ATB diff, since he has put that in, he is chewing through front tyres at a great rate.

At normal road driving speeds within the law there is no real advantage, but if you push it then the benefits become obvious.

Any diff which limits the differential speed between the two driving wheels, will wear the tyres more than an open diff.

I agree with the tire wear but disagree with the lack of an advantage... especially up here in the northeast.

Ah, yes, good point, I didn't think of that....We don't have those type of conditions here so I wasn't thinking of that scenario.

Costwise, initially looking to cost you guys over in the USA circa $3000USD plus shipping from the UK. Circa £2000GBP (plus VAT if you're in the EU).

It's based on interpretation.... the vehicles will still use the Viscous coupling but that technically isn't the center diff.... the front and center are actually two units in one as the center gets power from the output shaft and distributes it front and rear... that's my understanding and interpretation

Thanks for the clarification, its a bit confusing with the post where he has the picture of the front, and says its the front....
I just assumed that was what we were getting.
Anyway, that's good news, I have sent a message last week to find out more about it all, but haven't heard anything yet..
Might give him another message...

Yes thats right Eric, the viscous coupling is not actually the front diff, the centre spider gears are in the front housing along with the front diff...
This is part of what makes it all a bit difficult to design and build something economically....but looks like quaife have done it...

Oh really, that's a bummer, would be much better if it didn't use that, well, better for my situation at least.....

For anyone who is uncertain and to clear anything up, this unit still requires the use of the viscous coupling.

The unit is the front and center replacement, as per the stock unit setup of two diffs together, yet these parts now both feature Quaifes ATB technology.

It is an absolute work of art. We have the first paid units heading out the door this week across the globe :)

Thanks

If the centre is still a viscous coupling how can it also be an atb ?

If you look at the exploded view of the transfer/front diff you can see how it works.

The VC is in its own carrier where the transfer (centre) crown wheel and pinion is, then within the Front Diff Carrier, the spider gears are located for the Centre Diff.

A diff always has spider gears LSD or not, and in the instance of this GT4 setup, there isnt enough room for them in the center carrier with the VC...

Hope it makes sense....

This is why its not an easy solution to make something....

I would like to use the ST165 transfer which had the hydra-lock, that way it can be run open, so you get the benefit of the ATB for the centre, or one of the 185 boxes which has the Towing setting where you can disconnect the rear....that would also work....
This is also why this 4WD setup can never be more than 50/50 rear/front drive, as the front is always driven, so it can be more drive to the front, but never more drive to the rear than the front...

So the quaife solution has an atb diff and the viscous affecting drive to the rear ?

Mikes post states that his offering replaces front and centre BOTH if which are atb

Yes, the front is ATB, and the centre is ATB/VC if that makes sense.

Its all because the front spider gears, and the centre spider gears are all the front carrier, that's what is a bit confusing

KAAZ dumped the viscous coupling and stuck the center there [where it should be]. Seems pretty straightforeward to me. :P

Is the 165 center diff in the T case? For the locking diff type.
How do you plan on getting power to the rear with the 185 if you disconnect the rear? You're mechanically disconnecting it so no power goes there.
