A disk drive suspension and method for design of a disk drive suspension where the suspension has a load beam with a rigid portion and a flexure comprising a frame attached to the load beam rigid portion at a welding point. The frame has left and right outriggers and a tongue between the outriggers and cantilevered from the frame at a flexure offset rail. The tongue has a free end for carrying a slider in gimballing relation in operative proximity to a disk. The tongue free end being angularly displaced from said load beam by a dimple at a dimple contact point located according to the formula:where I1 is the moment of inertia of the flexure tongue (excluding the outrigger portion)I2 is the moment of inertia of the flexure outrigger (excluding the tongue portion)b is the length between the dimple contact point and the edge of the flexure offset rail and,c is the length between the dimple contact point and the welding point,whereby the suspension is substantially free of change in pitch static attitude angle through variations in the vertical height of said dimple and corresponding vertical displacement of said dimple contact point.
