Q: Who should attend?
A: Anyone who wants a better understanding of the factors that impact chassis set-ups. All of our seminars are open to all, and are attended by people who are involved in many different forms of motorsports. We gear some of our seminars specifically for quarter-midget participants, however. In the past our open seminars have attracted people involved in mini-sprint, Legends, midget, sprint car (both dirt and asphalt, winged and non-wing), supermodified, UMP modified and late model racing.
Q: What are the hours?
A: We start at 9 a.m. and stop at 5 p.m., with a one-hour break for lunch on your own. Please pack a lunch or plan to eat at a nearby fast-food restaurant.
Q: What should I wear?
A: Casual attire. Some of our seminars are held in race car shops. They can be drafty, so please dress accordingly.
Q: What will you cover?
A: We’ll discuss items relating to the set-up and operation of a race car, including the items that make up the “Pyramid of Grip”: spring rate, shock dampening, tire pressure, chassis roll, and chassis bind/chassis flex.
We’ll talk about maintenance, chassis set-up and analysis prior to the race weekend, a complete overview of the engineering forces in play, and how to choose the proper changes to make at the track.
