Adjustable strut rods

Heim joints are probably just fine on a car that will see only a few thousand road miles a year and get regular maintenance (although I'll never put them on a Jeep again). Keep them clean and lubricated and you'll be fine. Will they last 150K miles? Doubtful, but do they need to?

The issue with moving the pivot point back towards the arm, which a heim will tend to do, is that the LCA end will move in a tighter arc as the suspension goes up and down. because it moves in an arc, there will be some change in effective length and therefore caster. But since most of the time when we modify the front suspension we increase the wheel rate (bigger bars) and reduce the amount of travel (lowering). I suspect the amount of geometry change is pretty insignificant. The ability to adjust the length of the bars without taking the suspension apart is probably of greater benefit.

Sometimes Ehrenberg gets a little hung up on the little details and lets the "perfect" be the enemy of the "probably good enough."
