Hello, Want to say thanks for the program. I made several posts for you to look at in the new member section. Here's a direct link. Thanks again, and enjoy your time at the track... oh and I saw another thread on cold tires, remember the track is cold too and takes longer to heat up the line so to speak. Also race tires are made stiffer and have to be pushed a ceratin point to flex and heat up. Basic tires for us lesser humans are less stiff flex more and heat up quicker.
