sspano01... you asked about 2 1/2 degrees negative camber on the street .... don`t do it as it wiil eat up your tires on the inside . It`s a pain , but I reset my camber etc before track time and then reset it for the street after the track . As you get faster , you will find that your brakes will probably not be good enough . I have street pads and track pads and change before going to the track and then after the event . Again , it`s more trouble , but keeps you from not being able to stop once you really start using the brakes hard . The ducting others mentioned is pretty much a must in my book .
You asked about my Avons and tire pressures . I start at 25 psi COLD on the front and 23 psi COLD on the rear . You will gain as much as 10 psi on a hot track after the tires come up to pressure . Just take it somewhat easy for a few laps until you get some heat in the tires .... you`ll be able to feel it .
Measure your tire pressure right after you come in and see what your buildup is . Take some white shoe polish and paint the inside and outside edges of you tires to see how much they are rolling over .... old school , but it works and is cheap . Tells you if you need more air or less .
Keep a detailed log book so you know what works and what doesn`t .... and I mean record everything ... air temps , clear , cloudy , everything .
Otherwise , have fun .... which you sound like you are already having .
