Jack is correct. My research and past experience is the same - a front anti-roll bar doesn't do much, if anything at all. Driving into a turn, the car's center of gravity is transferred to the left or right rear corner where the tendency to roll is most pronounced.

I'm curious. My understanding is the A6 with Sport pkg has the same stock ARB as an S6. If it's the same 20.7mm, I wonder what a non-sports stock A6 ARB measures.

From ETKA

4G0 511 305 G / PR-1BA (standard) 19.6mm $181
4G0 511 305 E / PR-1BR (comfort) 17.3mm
4G0 511 305 D / PR-1BE, PR-1BV (sport) 20.7mm $165


The PR-1BR model code seems to be tied to older models as well as the nomenclature "rough road equipment", whatever that means.

*edit1* more info from the C7 study guide:

There are three dimensions listed for the RSB on the C7 A6, they are 17.3, 19.6 and 20.7. The strange thing is it is listing the "Standard suspension" PR code 1BA as 19.6MM, I am not sure what vehicle gets the 17.3 but I will continue searching since now I am curious

Ok, figured it out, the 17.3MM RSB is for the "Heavy duty" suspension which is also listed as "Comfort" in the field where "standard" and "Sports" are listed. The comfort part makes sense to me but not the HD part, I would think a heavy duty suspension would utilize a larger RSB...

So, if I decoded the last two posts correctly, the U.S. A6 standard non-sport uses a 19.6mm and the A6 w/Sport pkg and S6 use the 20.7mm. The Stasis ASB is 25.3mm.
Sound right?

Also, I wonder if there is ANY increased stiffness to ride comfort with the Statis ASB over the A6 w/sport pkg or S6 stock? My experience was with my non-Sport 2001 A6. I added an Audi OEM sport pkg ASB and while handling was vastly improved, there was no degradation in ride. However, I went from something like an 18mm to 21mm ASB as I recall. Not sure what going to a 25.3mm from 20.7mm would do to the ride on the A6 Sport.

It makes sense if you tie it to the "rough road" description, implying it's for off-road use or roads with lots of bumps or pot holes.

I found no change in the ride quality going from 20.7 to 25.4mm on the RSB, but overall the roads around me are relatively smooth.

Thanks, Rob. Unfortunately, most roads in New England can be an obstacle course of lousy pavement and potholes. That's one reason I'm looking to reduce the body roll - I do a lot of gymkhana-like moves to avoid them.

Perhaps Jack@Stasis can chime in with some further info on the ride characteristics.

Final question: i read your thread on the install and I presume you did it yourself. Since I'm of the non-DIY persuasion when it come to car mechanicals, short of calling them, any idea what an Audi/Stasis dealer might charge for an install? (There's no indy Stasis dealer anywhere near me).

Good point, I wasn't looking at it that way.
