Suspension Geometry

• Controls Toe Angle Movement

• Controls Camber Gain

• Controls Ride Height Movement

• Good geometry gives the springs, dampers, and anti-roll bars more influence than the geometry itself

To manage priorities, ask four questions about every design decision, in this order: 1. Is it legal or illegal? 2. How does the change affect reliability or repeatability? 3. How does the change affect overall vehicle performance over a lap? 4. What are the drivability effects?

The very best drivers can go up to but not over the maximum lateral capability during braking and corner entry. As they smoothly come off the brakes, the lateral limit increases due to both the friction circle, and more balanced loads front/rear.

Defining requirements, validating models, on-car tuning, and understanding the root cause of problems. The process of developing and troubleshooting a steering system.

Chassis, mass, and aerodynamic interactions affecting steady-state balance, and the purpose of anti-roll bars.

Definitions of limited slip differential types and performance, focusing on yaw moments due to combined cornering and acceleration or braking.

Skidpad testing, understeer gradient, handling and driver feedback, simulation with tire force and moment data.
