In order of importance:
. Make sure your bike is clean, and polished! Someone might be there taking pictures, and you want to look your best.
. Tell anyone within earshot that you're going to run in the slow group to "dial in your new suspension settings". Chicks will dig that.
. When you're not on the track, walk slow circles around your bike muttering, "man, I just don't understand all this chatter going into T3" note: This looks even cooler if you have a wrench of some kind in your hand. Bonus points if you pause to tighten somthing.
. Again, w/in earshot, declare your mission to ride the entire day without touching your knee pucks since the two pairs you went through last week were so damn expensive!
. Constantly monitor things like fuel consumption and tire pressure in the pits. Record everything in a small notebook with the intention of loading it into your spreadsheets for analysis when you get home.
. Finally: relax, and have an awesome time. Success will be gauged by the size of your grin at the end of the day. As for the rest of the stuff, I don't know if it works or not. I just learned it from watching Chills.
