Mazda tribute front diff looks the goods

How do you connect it to the chassis?

Im sorry to say it but, a change from the standard live axel to this type of rear end would just add weight and complexity for little reward.

Camber and toe adjustments can be made on a standard diff housing. And if more than 1deg of neg camber is required, a fully floating axel can be employed with only a little increase in weight.

The extra weight of things like the CV`s, floor reinforcing and brackets to hold the diff in place aswell as the De Dion tube would nulify any percieved benifits.

I doubt there would be much improvement in unsprung weight,
and im very confident that total weight would be a lot higher than the standard diff. Even using an alloy housing. This extra weight would surely be a backwards step in total performace, even if there is a slight improvement in unsprung weight.

The only advantage i can see, is the prevention of spring wind up under heavy acceleration.

Isn't the LSD a benefit too?

Only if the car has a traction problem. otherwise an open diff will be better.
If one is required, it would be a lot easier to fit one to the live axel than go through all this.

Im not saying dont do it, but for all the work and questionable total gain, personally i`d rather work on other areas of the car.

I would be interested in seeing it finished all the same.

By the way the DD setup is for the kb10 or tudor not vb10.
Floating hubs are expensive unfortunately and live axle LSD
are getting expensive and most are heavy bar the ALFA ZF,
If I break the ALFA I`ll be up Ship creek so best sell em!.
The Alfa ZFs (which will fund this project)

I actually expect it to be equal or lil heavier than H190.
It would be unique for a datsun & LSD centres like that
for Mazda/subey are more common & cheaper than live axle.

After driving an 81 Alfa GTV6 I was sold on it, its so predictable
with controlled sliding an absolute breeze.

So far Ive gone back to the Mazda miata obx centre is
supposedly a good Helical unit so for 280usd its cheap.

single leaf 360 from volvo is supposedly a winner!!

Nice links there.
Volvo springs sounds pretty good but it does mention there were very few imported.
OBX is a winner too with some modifications.
