1. A toy model vehicle suspension, comprising:

  • a toy model vehicle chassis;

    a first wheel for supporting at least a portion of the toy model vehicle chassis above an underlying surface;

    a first spring for providing a supporting suspension force to the first wheel, wherein the first spring is mounted to the toy model vehicle chassis for deflection within a range of first spring travel;

    a first damper for providing a damping suspension force to the first wheel, the first damper having an elongated shape, wherein the first damper is mounted to the toy model vehicle chassis for actuation within a range of first damper travel that is substantially equal to the range of first spring travel;

    a first suspension member secured to the toy model vehicle chassis for supporting the first wheel, the first suspension member mounted for a range of first suspension member travel at substantially a location of the first wheel, wherein an average motion ratio of the range of first suspension member travel to the range of first damper travel is at least about 2.5;

    a first coupling mechanism configured to transmit the supporting suspension force from the first spring to the first wheel through the first suspension member, while allowing movement of the first suspension member substantially at the point of supporting the first wheel; and

    wherein the first wheel comprises a first tire, wherein the first wheel is supported by the first suspension member for movement of the first wheel and the first tire, and wherein the first wheel and the first tire have a range of vertical movement at least about half of a diameter of the first tire.
