i never got the endlinks with my s/t sways, so i just hacked up some es bushings and used the stock one. well i picked up the closest es match, but of course the middle collar is a tad longer.

so what are the effects of a longer or shorter endlink? afaik after reading some of your crx setups, if i lengthen the endlink which would force the bar up, it increases stiffness.

not sure if the s/t endlink is even the same size as the stock one.. i got the 23mm rear for my 90teg.

 

None, unless there is binding involved.

The only reason to change the length of the endlink is when you drastically change the ride height of the car. This helps keep the bar from binding.
Try to keep the bar parallel to the ground.

 

^ What he said.

Assuming both sides are the same length and the bushings are not binding, the length has no effect. As long as the bar isn't hitting anything and the end links aren't binding up, you should be fine.
