Biggest problem with stock strut rods is the bushings. Stock rubber is too soft, poly has poor articulation as mentioned.

Aftermarket heim setups are so poorly designed that whomever did that needs nutkicked.

Think about the new location of the strut rod's pivot point and how the LCA will act as it goes up and down.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
