Why wouldn't I use Aquamist on the street?
I haven't done any passes like that, so I don't have a good answer for you. The only time I ran on APR's current code (v2) on 93oct, I did 12.23@115. That was with open dumps. I also had my seats removed, but that's less of an issue as that puts me close to sedan-weight. The dumps do make a difference though, about 1-2mph traps from what I saw previously. So, figure I'd trap about 113-114 with closed dumps.

nope - it was the first run of the day which I decided to start with it off...
(I had it off the last time out when I did the 11.949 as well - that was a cooler night though, so didn't see the need for it) after that first pass, I turned it on, and left it on for the rest of the pulls. It didn't seem to make a difference in my times/traps (unless someone wants to claim it hurt my times since the others were all slower), but I could see the temp difference in the logs.

depends what you are comparing to...
I don't have any data supporting that the 17" OZ (~18lbs) wheels have really helped all that much compared to my previous 18" Racing Hart ST6 (~24lbs). Perhaps it would be more noticeable compared to my 18" RS4 reps, for instance.
The tires, however, are certainly better than the ones (bald, busted, PZero Neros) I took off these wheels. At the same time, these (MX) tires aren't anything special. They're a $99 tire that I can put a lot of miles on and still drive to the strip and make some solid passes.
Here's what came off the car:

You can see the difference it made to the last 2 times I went out with these new (MX) tires instead of the bald ones:

However, if you also take a look at the group of data points at "121", those are from 18" RS4 reps w/ Kumho 712 tires and full interior. Those 60's are not bad at all considering that.
(1.937 1.939 1.79 1.815 1.923 1.988 1.895 2.098)
Passes 0-115 are with my 18" Racing Hart ST6 wheels with Kumho 712 tires.
Passes 125-160 are with 17" OZ wheels and used Pirelli Pzero Nero tires.<ul><li><a href="http://ctny.audiworld.com/mark/s4/wheels/">http://ctny.audiworld.com/mark/s4/wheels/</a</li></ul>
