Huh?
Exactly the opposite. If you run poly LCA bushings you really should use adjustable strut rods so you can tune the length of the strut rod so there’s no binding in the LCA.
The factory tolerances were loose, they got away with it by using large, soft rubber bushings. If you start taking slop out of the system by installing poly bushings, you need ways to adjust the suspension to compensate for those loose factory tolerances.
