== Suspension Compliance and K&C Mapping ==

K&C rigs measure hardpoint movement under applied loads.

|-
| Toe compliance
| < 0.08°/kN lateral
| Controls oversteer/understeer behaviour during cornering loads
|-
| Bump steer gradient
| ~0.12° per 10 mm bump
| Affects stability and steering response at high slip angles
|-
| Roll centre migration
| < 2 mm/° roll
| Maintains aero platform and balance during lateral loading
|-
| Camber gain
| ~0.2° per 25 mm compression
| Preserves tyre contact patch under heave and roll
|-
| Compliance steer
| < 0.05°/kN lateral
| Ensures predictable handling at 3–5 g lateral acceleration
|-
| Scrub radius
| 10–15 mm
| Influences steering feedback and kickback under braking
|-
| Caster trail
| 18–22 mm
| Governs self-aligning torque and yaw sensitivity
