History: On my old B6 A4 (V6 quattro TDI, remapped to ~220bhp), there was a common upgrade to replace the rear anti-roll bar with the stiffer RS4 version. This had the effect of almost completely neutralising the understeer, to the point where you could actually get to the point where, if you were on a low traction surface (snow, gravel or wet road), you could feel a little bit of understeer, but then use the throttle to generate very controllable power oversteer. Probably less advisable on to smaller TDI's (narrower, more "spikey" power band), but it was great for the 1.8T/3.2FSI!
A6 C7 concerns: I know with the rear torque bias and numb electric steering, this could be more risky, but I'm keen to get a similar effect on my A6: is there a recommended version of this upgrade for the C7 chassis? As I said, the initial reaction was previously still a little understeer, but overall very neutral.
What to replace? Since I'm only trying to tighten up the rear, do I go for the same as my A4 and only replace the rear sway bar or is there something that ought to be done with the front too? Is there a better way of doing this with the A6?
What to go for? Assuming it's just the rear sway bar: Is the S6 sway bar enough of a step up? Would an RS6 rear sway bar be too stiff for some A6's (since it is a heavier car than my s'charged V6 petrol)? Better aftermarket options?
