Anyone happen to know what material was used on the factory a-arms. Is it a mild steel or carbon steel such as 4130?

K

Mild steel is 1018 and 1020 or higher. Pertaining to the % of Carbon in the (Iron) Absorbing Oxygen and Creating Steel.

4130 is 'Chrome-Moly'. (banned for Roll Cages by Race Sanctioning Bodies, as 'IT' Does Not Bend, Easily, before the Welds Snap). As is My Understanding.

To Increase the +Positive 'Caster Angle' the (Front) TOP/Upper Ball Joint is Moved REARward. This puts the TOP Ball Joint farther to the Rear in Relation to the Tire 'Contact Patch' to the Road Surface. It Does Increase the 'Centering Effect' of the Wheels, and Increases the Steering Effort.
