Alternative diff choices?
I've been pondering that perenial question of alternative diff choices.
Audi have made quattro 4wd cars for many years - would the rear diffs be useable?
I'm guessing the ratios may not be right, but they should be OK power/torque wise.

Reading a bit on VAG 4wd systems it appears cars with transverse engined 4wd systems have a non permanent "Haldex" drive system which uses
a clutch to engage RWD only when the FWD starts to slip/slide.
Maybe that rules out theses diffs?
What about the larger/longitudinal engined 4wd VAG cars?

Freelander diffs are becoming common in newer kits as the sierra ones become older.
I cant see the sierra ones becoming scarce anytime soon but eventually people will need to look else where.
BMW 3 series?
MX5?

I have a 2.28:1 BMW diff (from 330D) that may eventually find its way into my car. It's heavier than the Sierra unit, but lighter than the Jag
IRS I was going to use.
There are dozens of ratios available.

I would have thought BMW would be the easiest option in terms of choice and availability in scrappies / on eBay.
Whatever you use there will be issues making driveshafts to fit if you stick with Sierra rear uprights though.

I always wondered why the front wheels seem to slip when i dump the clutch on my octavia 4x4.
