Tire Pressure

changing rear tire press on street tires is dumb. it's not going to gain you anything.
airing up the fronts does make sense since you're decreasing rolling resistance....every little bit helps!

Tire pressure on regular old street tires doesnt really offer much in gains. If underinflated, the middle of the tire wont contact the pavenmant as well, and if over inflated, well, obviously thats not gonna help either. I woudl just run the reccommended pressure for that tire and beat up the clutch to get a decent 60' 
. DRs and ET streets/slicks, are a whole different ballgame.

I know this Doc... but just recently at GLDW @ Chicaco 2006 we had 40/40 tire pressure (front / rear) on my friends mk2.
We went to the setup that I posted, and he knocked almost 3 tenths off the time.
when I drop the tire pressure in my goodyear eagle ls's I spin 1st 2nd AND 3rd instead of just first and chirp second.
With street tires it will take some playing with. I'm sure each one is different. You might see gains by going up or down. Enough messing around and you can fine the right combo. Comming from the domestic group I now this little thing can make all the difference in the world, especially to a non-slick run. When you are running dot tires pressure is more important than almost anything else.
