Quaife Automatic Torque Biasing (ATB) Differentials
#1
Hi
I have noticed that Demon Tweeks are selling the Quaife diffs for £525 each (front and rear separately). See DT Motorsport 2000 catalogue - page 201.
Has anyone fitted or used them on a car before and what were the results ?
Do these work in a similar way to the "Torsen" diffs which were fitted to Audi Quattros ?
I'm not likely to buy them myself (it has to be said) but I am curious to any potential pros/cons for using these instead of the uprated STi viscous diffs.
Thanks
Gavin

There is also a potential issue with the ATB diff as well in that if you end up with one wheel with no traction at all then it provides no power to the other wheel. I dont know exactly what the definition of no traction is but certainly that wheel in the air causes you to loose traction. Caterham are replacing this sort of diff on the caterham race cars with a more traditional plate differential because of this problem.
I have been talking to Quaife about these because of some future plans I have.
It might be worth pointing out as well that a Viscous coupled differntial is really a speed differential limiting device in that it doesnt start to work until one wheel is travelling faster than the other.
Mindst you we dont spend that much time with one wheel in the air or do we?
