Hi everyone, I was hoping I could ask a favor from an Ap1 or Ap2 owner and that was to measure their rear stock sway bar and tell me the bushing to bushing measurement, end link to end link measurement, and the bushing to end link measurement. I am looking to see if it is at all feasible to modify the sway bar to fit other Hondas. I greatly appreciate your help. Thanks.

 

Here are some estimates. They're based on a combination of my direct measurements of somewhat different dimensions (see Table 4 of my "Characterization" paper, linked in my sig and stickied at the top of this forum), plus some Honda schematics. Please note that although the numbers are shown to the nearest 0.1in., the true precision is certainly much worse. But hopefully this gets you in the ballpark for a basic fitment check.

(1) Endlink to endlink: 40.7 in.
(2) Bushing to bushing: 30.2 in.
(3) Endlink to bushing, horizontal: 5.2 in.
(4) Endlink to bushing, longitudinal: 8.5 in.
(5) Endlink to bushing, vertical: 1.4 in.

Notes:
(1) Distance from mounting hole to mounting hole. This is calculated from the dimensions defined in the Characterizations paper, and is equal to L + 2*(C^2 - R^2).
(2) Distance between the vertical centerlines of the bushings. Calculated by subtracting twice the value (3) from the value (1), i.e., 40.7 - 2*5.2 = 30.2. (Slight discrepancy is due to rounding.)
(3) Distance from the vertical plane containing the endlink mounting hole to the vertical plane through the centerline of the bushing. Calculated from a Honda suspension schematic, using the AP1 rear bar diameter (27.2mm = 1.07in.) as a reference measurement.
(4) The lever arm R defined in the Characterization paper (R=8.5in. for all rear bars).
(5) Distance from the horizontal plane containing the endlink mounting hole to the horizontal plane through the centerline of the bar as mounted in the bushing. Calculated from a Honda suspension schematic, using the AP1 rear bar diameter (27.2mm = 1.07in.) as a reference measurement.
