About the Course
The physical layout of a typical car control clinic event will depend upon the
facility. Our previous events were held at Southwest International Raceway (SIR),
in Tucson, AZ, in the parking lot of the drag strip. For such a clinic, we provide
three different "stations" that run simultaneously during the morning sessions. No
timing is done for these exercises. The stations are laid out such that there is no
close association between the stations and the possibility of a collision is avoided.
The entrants are split into three groups, each group is assigned to a station for
an hour. During the course of that hour, each student will drive the exercise
multiple times. Each student is accompanied by an instructor for each pass through
the exercise. Multiple instructors are available at each station so the students
have different instructors throughout the session. We usually have 8-10 students
per exercise so there is a car on track, almost continuously, on each course. This
means that all of the students get a lot of track time and that is essential to our
teaching efforts. At the end of each hour each group moves to an adjacent station and
begins a different exercise. The morning sessions are concluded when all students have
completed the exercises on each of the three stations. This arrangement also allows
drivers sharing a car to have the full experience. We consider that a student spinning
their car during any exercise is a bonus and quickly point out that no harm was done.
Instructors follow up with questions about why the spin occurred and ask what could be
done to avoid the situation. This also provides an opportunity for the instructor to
praise or comment on car control efforts used by the student and to teach these techniques
when found lacking.

About the event - the morning session
Station 1
The first station consists of two adjacent circles or skid pads, one somewhat larger than the
other. Initially the goal on the larger circle is to bring the car to a steady speed that will
allow the car to circle at a set distance (about 6-10 feet) from the cones defining the circle.
Then the student is instructed to increase the speed in small increments until the car tries to
deviate from the previously set distance. The new goal is to modulate the throttle setting,
without changing the steering angle, to maintain the set distance at a speed that is at the
traction limit. In other words, students learn to throttle steer the car. This exercise allows
the student to begin to understand weight transfer and its effect on cornering. When this skill
has been mastered, the students are instructed to deviate from the single circle and begin
navigating both circles in a figure eight. This requires modulating the throttle around two
distinct settings, each ideal for the two different sized circles. The figure-eight exercise
allows the students to gain an understanding of the need for smooth throttle and brake application
while maintaining smooth and steady steering inputs.
