What car do you have? Do you want to use the tires for just track or do you want to street them too? What % street/track will the car see?.
The driving courses are usually one day or a two day weekend. You will see about a hour on track in a one day course. If you just want track time I would recomend open track days with one of your local track bookies. What part of the country are you in? Out here in the west,
http://speedventures.com will get you 2+ hours of in the seat time and we do offer instruction. We do lead follows to teach the "Line" We do ride alongs or drive your car for you. We give ride alongs in our cars. When we have a lite turn out we allow you to run extra sessions. I have seen some guys get 4 hours of on track time in one day. They went home tired LOL
