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 substitute for a lack of
racing technology 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.
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.
The 2008 RaceWise Program
All critical aspects of chassis set-ups, tuning and tires are covered in an easy-to-learn, step-by-step, organized, racer-friendly

RaceWise History
The RaceWise Dirt Track Chassis school is owned and operated by Mark Bush, co-founder of AFCO Racing Products. Mark's
ongoing racing experience includes over thirty years of designing, building, testing and developing race car suspensions and
components. Through AFCO, Mark is regularly consulted by both chassis builders and racers, from dirt track to NASCAR, for his
technological expertise. Mark authors most of the technical information provided by AFCO and provides select suspension
articles for various racing publications.
The roots of the RaceWise Dirt Track Chassis School go back to 1984 although the school was officially named "RaceWise" in
2002 to distinguish it from others. The school has helped thousands of racers, from hobbyist to World 100 winners, improve their
racing knowledge & skills. Students from almost every state plus Canada, England, New Zealand, Australia and South Africa
have benefited from the three day school.
