Ive been considering methods of incorporating adjustability into my suspension design on the custom chassis ive been working on and am wondering if anyone can shed some light on the methods i've though of, and tell me if they are good ideas, or shouldnt be tried.
My Goal is to have adjustable, caster, control arm angle front to back for anti-dive.
As most of you know, you can tune out anti-dive in the front by angling the control arms. If you look at a side view of the chassis with control arms drawn, if you tilted the control arms so that lines extended on their planes intersected at the center of gravity, you would have 100% anti-dive at the front, and if you did this at the rear, you would have 100% anti-squat.
Now, this is going to be difficult trying to describe without pictures but ill do my best. this example is assuming you are using spherical rod ends to link the control arms to the chassis. If you tilted the rod ends horizonal, you could put larger or smaller spacers on top or underneath the sperical joint at the front and rear joint of one control arm. Using different sized spacers at the front and bottom would make one end higher than the other, This would tilt the control arm right? And the spherical joints would still be perfectly horizontal. Would this still be effective way of introducing anti-dive technology? or would the spherical joints have to be tilted with the control arm to get the proper arc travel?
My next adjustment goal is caster, in this example you are using spherical joints to attach the control arm to the chassis. The sperical joints are oriented vertically in this example, with spacers in front of and behind the joint. Using larger spacers in front of both sides of the top control arm, and bigger spacers behind both sides of the bottom control arm would place the bottom control arm further forward than the top control arm tuning in some degree of caster right? So could you just use different spacer sizes to adjust the angle of caster you want?
if there is an easier way to go about doing these, please let me know, im just trying to cover my ass so i dont have to be stuck with my original suspension geometry design forever if it turns out to be less than perfect.
