   "Anti-dive is the braking counterpart of anti-squat: geometry that limits how far the front compresses when braking. On a full-size car it is a percentage: the height where the tyre-force line through the side-view instant centre crosses the CG plane, divided by CG height (Formula1-Dictionary).",
   "On RC cars it is the front inner hinge-pin angle with the rear mount higher; a steeper angle adds anti-dive and corner-entry steering, reduces front weight transfer under braking and decreases caster (CompetitionX).",
