Update to this discussion...

I installed H&R bars and adjustable end links this week.
After corner balancing the car (links disconnected) when reconnecting the bars there was definitely a significant adjustment required to the links front and rear to eliminate pre-load.

Front there was aprox 3/4" difference and rear was about 1/2" difference.

Also regarding need for only one link.
This is true to eliminate pre-load, but you need two if you want to change overall position of the bar angle.
This is especially important at the rear where clearances are very tight between the wheel drive shaft and lower camber control arms.
