allroads at PIR (long)
Audi Club Northwest did a weekend at Portland Int'l Raceway last weekend - two of us allroads showed up (me and yzf996fxdwg). Since the last time I ran here (last Nov.) I lowered it and changed to 18" rims and S03s - what a difference!!. The best lateral g's I could get with the stock Goodyears or my winter tires was 0.8g - I was consistently running 1.0g last weekend.
Here is a shot of the two of us entering turn 12 (old turn 9).

Yzf996fxdwg has stoptechs - no way could I keep up with my original pads and rotors. Well, these two days finished the pads (and maybe the rotors too), so at least I'll have new stock brakes soon. Yzf996fxdwg was nice enough to volunteer to keep in formation for a few laps for the photos. Here we are exiting the same turn heading onto the front straight.

A couple of folks noted that I seemed to be cornering flatter than yzf996fxdwg. I think these photos also show this difference. Judging by his sig (I forgot to ask) - its my PSK rear sway bar which makes this difference.
Here is a couple of more - I'm in the center of that corner.

Here is Yzf996fxdwg a little further along in the corner.

I'm really pleased with the way it handles now. Although it's still a load to hustle around tight turns, it is pretty neutral and with the S03's - very controlable. With this set up I could pretty much stay with the stock S4s - but I really need brakes.
There was all the track time you could wish for and a "quattro-friendly" variety of weather conditions. A good time.

Great shots! What did you use to measure lateral grip? (G-Tech or some such thing?) ->
By the way, you could give performance brake pads and brake fluid a try, in lieu of changing the whole brake system. Those two things alone should give you considerably better fade resistance, and improved "bite" on the track.
I found that replacing the brake lines themselves (to improve pedal feel) was not a very cost effective upgrade. Best to save that for the full system change.
Oh, I think YZF had a little bit more <i>flavor</i> in his tortilla... which might further explain your inability to keep up. =)

His octane rating was a little higher...
but my gas mileage was better ;-).
I used an AP-22 (like a G-Tech).
I'm not sure which way to go with the brake upgrade yet - thanks, it's something to think about.

Re: allroads with 18in wheels
wow great pics, sounds like you had fun.
how do both of you like the 18s for everyday driving? i have put snows on my stock 17 avus wheels (255x40) and am about to buy new wheels&tires for summer. considered going plus one to 18s but tires would drop from 40 series to 35 and i'm not sure about daily drive utility.
i used to live in the nw and hope to come up for an event this year.
any s6 wagons at the event?
regards

Re: allroads with 18in wheels
I also have "winter" tires on my stock rims (17"), so Ive gone from 225/55/17 to 245/45/18. I think the changes I'm noticing are more the S03 tires than the larger rims, but at relatively slow speeds it follows changes in the road (tramline) more and it takes more wheel input to keep it straight. At higher speeds I don't notice that as much.
I haven't been driving the backroads with these wheels and I think I'll just swap for my winter wheels if I do.
I think our air suspension is a plus in one regard - even with the 18" rims and stout sidewall tires, the rebound shock from hitting a bump (or hole) seems less than in a comparably-sprung A6. Even though you can feel (and hear) it when you hit a pothole, it isn't a harsh, jarring feeling.
No S6 wagons were running, but there was a 900 hp nitrous-powered Celica which burned rubber all the way down the straight and then couldn't really control it in any corners - and limped off with emergency flashers going.
