A few questions have come to mind, but first the basics of what I'm planning...instead of the typical spring behind and radius rod "suicide" set up, I'm planning on going with a spring over 4-bar configuration, with the lower shock mounts on the bottom end of the perch bolts. For upper shock mounts I was planning on using the forged F1 style mounts. Now for the questions...
- Is there any caster angle built in to the new axles sold by the likes of Speedway, Super Bell, Magnum, etc? I recently ran across someone who was selling actual Model A axles that he had dropped, and had 7 degrees of caster "built in". Until I saw that I'd assumed that all of the axles were straight, and caster was set entirely with the adjusters on the 4-bars or radius rods.
- Should the 4-bar frame end mounting points be perpendicular or could the upper bars be mounted slightly more rearward to have a bit of built in caster?
- From what I've seen, the lower shock mounts fastened with the perch bolt mount the shocks in front of the axle to the outboard side of the batwings. Would there be a problem with turning them around to mount the shocks on the back side of the axle, inboard of the batwings?
