WHY? why isn't the steering arm even with the spindle axis? it is positioned to set the Acremen. Acremen is the relationship of the steering points with the rear axle. To get "perfect" Acremen, a line from the center of the outer tie rod end, through the spindle axis, would pass through the center of the rear axle. This relationship allows the inside wheel/tire to turn slightly more than the outside tire in a corner. Remember that the inside tire must make a sharper turn in the same corner than the outside tire. Understanding Acremen in its basic concept will leed you to know that you can't change it much. If the wheelbase and front suspension width are constant, then only the steering arm will adjust Acremen. This is tough to do with the one piece spindle on the C-10's. You may not want "perfect" acremen anyway. A line that runs wider than the center of the axle will be an give you "softer" acremen, and be more stable at high speed. A line heading more inboard will be "tight" and have very quick steering reaction, good for go-carts. I hope this info helps to explain the basics. let me know if you have any questions.
