    "data": {
        "note": "Wheel rate = spring rate × motion ratio², where the motion ratio is the spring's movement per unit of wheel movement (usually < 1, so the wheel feels a softer rate than the spring's). A 200 lb/in spring at a 0.7 motion ratio gives a 98 lb/in wheel rate. Angle and leverage of the spring set the ratio — it dominates the feel.",
