These are intended with a stock ride height to be matched to the length of the OE end links, but shorter, or longer, does that not affect the bar rate? I understand an adjustable bar and how that works but first experience with adjustable end links. I think that these adjustable for lowered ride height and not making any contact with other bits under the car, right?

Within reason, changing the end link lengths won't change the rate significantly. By changing the angle of the bar's arms, you can alter the rate a bit and also the "curve" of rate gain/loss as the suspension moves and the arms swing through their arcs. But it won't be a big change. The big reason for adjustable end links is to adjust one end link's length relative to another in order to add or eliminate preload in the suspension/wedge. In a circle track car, this could be a useful tuning tool for handling balance, but on a car that has to turn both directions you generally just want to zero it out. However, it could be used to adjust corner weights if you don't have adjustable spring perches.

They went in easy-peasy, the bar was a real PITA though.

I've often appreciated them for providing the ability to actually use all the holes on adjustable bars when stock endlinks aren't long or short enough.
