MARTINSR good points, can't say I have ever seen a rack on a I-beam axle, but for the amount of movement in all the various directions required, it would be impossible to design a robust steering shaft that did not impart some change in the direction of the wheels when the axle moved through normal travel.
Something that the camaro clip has going for it that no one seems to give it credit for is that the steering geometry is DONE FOR YOU by GM, when you put your own kit on the front, it is completely up to the installer to get both wheels in the right spot, upper and lower A-frame mount locations side to side, front to back. I am smart enough to realize that I am not as smart as the chassis and suspension engineers who designed this stuff in the first place . . . actually, I might be smarter, I just don't want to take the time or make the investment to learn everything they already know
, if you are going to do a kit your measurement tasks and alignment skill requirements go way up. Me . . . I am sticking with a beam . . . simple and rugged.
