Improving handling on C6 A6
<center><img src="http://web.hisser.org/audi/audi.jpg"></center><p>I've had my 2.7 TDI from new and it's now just out of warranty so I want to do a few things to the car to give it a new lease of life.
I've already retrofitted AMI, and it's going to be re-mapped on Saturday from 180bhp to about 220bhp with heaps more torque
Now, I'd like to improve the handling of the car but without going too crazy. At the moment the car wallows around corners, it's like driving a boat! It would also be nice to lower the car slightly because it does look rather high.
What are my options? If I got lowering springs would this improve the handling, or just the look?
I'm in the UK by the way

Re: Improving handling on C6 A6
Maybe can give ABT Sportsline a go. They have a suspension kit with a set of trick dampers. Also can consider Bilstein PSS, I think someone from Audi Driver magazine converted a C5 RS6 with PSS & found good ride quality.

I thought about just H&R springs but I think I would need better shocks as well.
My A6 also feels large. Just last night I hit the gas to beat the light and the cross street is a little elevated so when I hit the "bump" in the road I felt the car rise shortly followed by the wheels and suspension and then back down again. Felt way more cushy than my A4 S-Line which probably would have hugged that bump at the expense of some ride comfort.

Re: I used eibachs and my cars seems to handle better, could just be me...
I got the eibachs and I think it is definitely improved. However, my rears are sitting lower than my fronts and I think it is wise to get better shocks as well. The stock shocks with eibachs. something is not quite right.

My mantra is to improve the suspension and reduce unsprung weight.
The accepted logic here is eibach + koni FSDs, with upgraded sway (or roll) bars.
I've preferred the OEM approach except for the Koni FSDs. One point of unhappiness with the FSDs is that one side is higher than the other in the rear, and there is obviously a defect. Am working with the shop that sold me the dampers, but I had OEM replacement Konis (red) on my C5, and they had to be changed due to squeaks. So am not persuaded by Koni quality.
On the unspring weight issue (rims, tyres and brake systems), you'll be surprised with the improved ride quality and ultimately handling. I went from heavy OEM Avus 17" rims from the B6 S4, and they weighed 29 lbs each. Changed them to the MTM Forged Bimotos at 19 lbs each, and even though I went up 2 inches, my ride is far more comfortable due to the weight (and inertia) loss. I also chose the lightest high perf tyre in the Conti CSC3s, which are roughly 2 lbs lighter than the equivalent Michelin PS2.
You could go the whole hog and instal the StopTech brake kit which also reduces weight, tho I don't know by how much.
Hope this helps.

Don't bother with springs....
...if you want the "wallowing" to stop you have to change dampers and springs. This is from MY experience...others might have different opinions. Suspension setups vary person to person, and the best way to guage what your particular feel is, is for you to go for a drive on a similar setup.
Recomd.--> KW variant 2 coilovers, maybe 1k lbs.
