rear anti-roll bar

Ive done the RS4 RARB mod and it does improve handling slightly, but you can only really feel it when you are properly chucking it about.

RE front ARB i was told they are the same diameter across the range A4/S4/RS4 so no advantage to upgrading.

DBSK, is your car FWD or Quattro? I've been thinking about getting the RS4 RARB but I'm not sure if it'll do any good to a FWD. A stiffer RARB should cause more oversteer, but does it do that in an FWD as well?

Mines FWD. Its definately worth doing, i wouldnt say it makes it easy to oversteer, if you really try you can get lift off oversteer but youve really got to chuck it in for that to happen.

But everyday it makes it alot more stable through high speed roundabouts/corners.

Which wheels are driven will not affect the corner entry phase which is the one that different ARB thicknesses has the most effect on. Even the mid-corner phase (most stably done under light acceleration) is not hugely affected by the driven wheels. Handling balance and traction are very different things, and which wheels are driven mostly has an effect on corner exit under power. So alterations to spring/damper/ARB settings will largely affect a FWD in a similar way to a Quattro, ignoring the weight differences...
