Mark Bush – Main Speaker

The RaceWise philosophy is simple: We believe you can’t fix or improve something (including racecars) unless you know how it works first. At the RaceWise Dirt Track Chassis School, students learn how suspensions actually work and how tires make side and forward bite. This foundation of knowledge enables students to learn not only WHAT to do to improve handling and tire performance, but, more importantly, they come to understand WHY! The knowledge we provide takes the mysteries out of chassis set-up and tuning and eliminates guesswork and misunderstandings that are so common for most racers.

Our mission at the RaceWise Dirt Track Chassis School is simple: help racers of late model, modified, and street stock-type dirt racecars improve their racing program. We provide help through education. There is no making up for a lack of racing knowledge given today’s level of competition. Winning takes making the right decisions in the shop and at the racetrack, no matter how good one’s equipment might be. RaceWise provides the technical understanding of suspension and tire performance that racers must have in order to make “no guesswork” decisions regarding chassis setup, handling analysis and adjustments to the racecar and to the driver’s techniques.

All critical aspects of chassis set-up, tuning, and tires are covered in an easy-to-learn, step-by-step, organized, racer-friendly manner.

Late Models – Modifieds – Street Stocks

  • Three days classroom: 8:30am to 5:00pm
  • Nightly Activities and Guest Speakers: See Event Schedule under Dates & Locations tab for details
  • Optional 1-Day Front Suspension Geometry School

Main Focus

As previously stated, the RaceWise program is based on a simple philosophy: You can’t fix or improve something until you know how it works. So, RaceWise students learn:

  1. How tires and suspensions actually work
  2. What actually determines how a race car handles
  3. How to determine:
    • What adjustments to make
    • When to make adjustments
    • How much adjustment to make
    • What set-ups and suspensions work best on various track conditions/types
  4. Why chassis adjustments affect handling
  5. How to adjust driving techniques for various track conditions and how to analyze driver performance
