Firm feel adjustable a body strut rods

MopaR&D said

I'd rather use ones that get rid of the front bushings altogether (replaced with a Heim joint or similar), to me that's half the reason to go with adjustable strut rods in the first place. Even with poly bushings the strut rods will compress them under hard braking and alter the caster, not something you want in a panic stop or when trying to make an evasive emergency maneuver.

The bigger issue with the poly strut rod bushings is the resistance they add to the up/down travel of the LCA. Their stiffness under compression is good to keep the LCA from moving fore/aft under braking and acceleration. But that same stiffness is a detriment to the normal LCA movement when the suspension travels up and down.

Which is why the heim jointed strut rods are better, no fore/aft movement and very little resistance at all for up/down movement on the LCA. Normally I’m not a fan of heims for street car suspension either, but the QA1 style adjustable strut rods on my Challenger did 70k street miles with no issues and no appreciable wear.
