A performance Driving school is highly recommended and will give you a lot of confidence knowing the limits of the handling/tires in a variety of situations, wet,dry and under some G's.
I've been to one and its totally worth it to go.
Its guaranteed that you will be a better driver because of it and the racing line theory part of it is priceless as there are a number of counter intuitive things you can do to get around the track faster, and understanding it will make you a better driver/racer.
Its also so much fun that some people go more than once.
