Audi S4 01E Quaife ATB differential

[viperbl]

So, first queston, anyone upgraded to this? I assume this is for the front, in the gearbox? secondly, will this fit my RS4 gearbox????

What kind of better performance should I execpt? Less "side to side" action as I accelrate hard?? Less understear in corners? (not that I get that much anyways!)

Or am I maybe better to go for a 80/20 centre diff instead and take away the power front the front wheels???

you should also consider a plate/clutch type diff which are better for track use, Gripper do them for front and back for 560 plus VAT

What kind of diff do we have in the stock RS4 unit?? I am really no too hot on the whole plate/gear clutch and whatever we have in ours at the moment...

Don't suppose anyone knows of any good reference websites that I can search on

Dodgedave has the quaife diff's in his rs4,he said there the mut's nut's

I think he said that he hopes they are. Car hasn't been on the road with them yet....

Its a fair amount of cash, but since the box is out, but then not sure what kind of differnce to expect, I mean, the car does seem to handle pretty well as it is ...

viperbl stasis's site have a good basic talk through what different diff's do

a rear lsd sounds to be fun on corners, quaife gear one sounds more refined for road use and track

its possible your rs4 centre diff is a 4:1 anyway, only a few were 2:1 as in s4 IIRC
