Lesson 6: The Full Alignment & Track Tune
Duration of Days: 3
Lesson Objective
SWBAT:
Perform a complete 4-wheel alignment (Camber, Caster, Toe) to precise race specifications.
Justify alignment settings based on a provided track map (e.g., a tight oval vs. a long road course).
If our goal is to maximize battery life, which alignment setting is the most critical to get to "Zero"?
How does a "neutral" handling car differ from one that "pushes" (understeers) in a corner
Understeer (Push), Oversteer (Loose), Neutral Handling, Tracking, Centering, Lap Time, Rolling Resistance, Scrub.
CT-CTE.TRANS.D.17 (Perform alignment); CT-CTE.TRANS.B.10 (Diagnose and solve transportation problems).
DOK Level: 4 (Extended Thinking)
This is the cumulative lesson for the unit. Students apply all geometry concepts to "Tune" a vehicle for a specific racing scenario, balancing traction against rolling resistance.
Misconception: "Once the car is aligned, it stays aligned forever."
Correction: Vibrations, bumps, and even the driver’s weight can shift alignment; it must be checked as part of every pre-race "Tech Inspection."
Support: Provide an "Alignment Symptom Map" (e.g., "If tires are wearing on the inside edge, adjust Camber").
Extension: Have students analyze "Tire Pyrometer" data (fictional or real) to see if the alignment is heating the tires evenly across the surface
The Crew Chief Challenge: Students are given a "Track Spec Sheet" and must align their vehicle to match, then defend their settings during a "Tech Briefing" with the instructor.
