RS6 handling...

If you are anywhere near the midlands, take it to Chris Franklin at Centre of Gravity in Atherstone just off the M42. His skills with the geometry of a car are well renowned in Porsche circles.

Update:

I changed the 21” wheels for 20” ones and fitted MPS4s all round. I had a Hunter alignment done at the same time and they reduced the rear toe-in to as low as it could be while still inside the Audi tolerance.

Result - completely different. Better ride, quieter, full-bore overtaking happens in a straight line and although camber and road surface changes are detectable, they are easily corrected with light pressure on the steering and are very muted compared to how they used to be. Confidence in the direction the car is going to go has returned and I am enjoying it much more. Interestingly, it had stayed exactly in alignment between the two visits, so the only change was to reduce the toe-in at the back to 5 minutes. Whether it was this alone or a combination of the better tyres and smaller rims (which is what the car was originally designed to run on) I don’t know but I’m not going back!

Are you on air or drc?

[Ed the duck]

Air.

[davers6]

I did a lot of research before buying a car read quite a bit about air cars lifting too much on front and squatting too much on rear might just me the price you pay for air

I can’t say I’ve noticed that in abundance. It’s normally pretty level - it was the tramlining and hedge-finding tendencies that I didn’t agree with...

Air car feels a little like in a boat, drc I think better for handling

If you look at a photo of an air car accelerating hard it is very noticeable.

I don't think the 20s had a great deal to do with it as I swapped regularly from my 20s to 21s and and my 20s were worse due to the Pirellis compared to the Michelins on my 21s.

The lighter (and stronger) 20s with Mich PS4S is the ultimate set up for the RS6 - as you have discovered

[Tadass910]

For the looks 21 all day long

[davers6]

My drc car does this too had the tracking checked was spot on you just have to be ready for it lol

From what I'm aware and from people I've spoke to about the roll on both air and drc there not to dissimilar.
I have air and in dynamic I noticed a considerable amount of roll whether in comfort or dynamic.

My suggestion whether you have either is to fit a new anti roll bar. I went with the 034 Motorsport roll bar. Ride is stiffer in dynamic and a lot less roll in comfort but still comfortable.

If 20's are the ultimate set up, then i'd rather stick with my 21's with Ps4's for the ultimate looks and put up with a bit of torque steer

[Ed the duck]

Beauty is of course in the eye of the beholder but I fitted some aftermarket Italian 20” alloys that look very similar to the Audi 21” items, and if you swapped the hub protector no-one would know they aren’t genuine. All IMHO but they look better in that size. They are also ~6kg lighter which x4 is 24kg: a significant amount of unsprung mass gotten rid of.
