I never gave thought to this. Thank you for the video.

Pitman arm and ackermann are 2 different things, ackermann (simplified) is the difference in angle between the left front and right front while turning. The different holes will achieve different ackermann along with changing the force needed to turn the tire with the steering wheel. Closer to the kingpin on the left front will get more ackermann and farther away on the right front will get less ackermann. My thought is that, in theory, on a larger track with sweeping turns, you would need less ackermann so that the front tires aren't fighting each other as much, while on a tighter hairpin style track, more ackermann should help get into and through the center of a turn.

Yes sir, what I’m referring to is what manufacturers call certain items. For instance, Phantom calls the connection point of the tie rods to the steering shaft is a “Pitman Arm”, Trick Olimpic calls it an “ Ackerman”. What you are referring to is Ackerman angle which I really don’t go into to deep in this video.

@@kartspeedsolutions gotcha. I guess I had just never heard it called an Ackerman lol. Didn't really mean to come off as arrogant or rude

Yes sir, no worries, didn’t take it that way at all😁

In order to keep my sons tie rods level and true, I had to put one tie rod in middle hole on the RF spindle , LF spindle is fast hole, Ackerman is fast hole. But everything is true and level, thoughts.

on the spindle the hole at the top is fastest hole at bottom is slowest. it takes more travel at the bottom and less travel art the bottom to move spindle same distance

No sir, when going to furthest hole from the kingpin on the spindle arm you are increasing the speed of the steering. Reason for this is because you are increasing the throw of the spindle arm which in turn increases the rotating speed of the spindle barrel and there by increasing the rotating speed of the spindle axle.

Further away from the spindle barrel, less angular motion. Thus slowing down the steering. Opposite is true on the steering shaft, further away from the shaft increases steering speed due to increase in angular motion.

@@kartspeedsolutions So would you recommend setting both sides the same hole? For example, both in middle, or both in front or rear? Would there be a situation where you may want to have them different on each side? Thanks in advance!

@@ryandavies6861 yes sir, I always set mine the same on both sides. Can you change the ackermann angle by setting them in different positions and get a different handle response? Absolutely. However, this would not be an adjustment I would recommend doing.
