This is the problem with a strut suspension as the arc of the control arm will create an effective shortening the strut arm as travel increases. Not ideal but certainly livable if you are running on smooth surfaces without a lot of suspension travel. On something like a dirt track racer, it could become more problematic unless the toe changes are measured and correspond to a desired angle.

The strut bushing being compressed under braking creates toe changes, which can make corner entry feel unstable as the car pitches forward, steering angle increases, and then toe takes you out of the line or requires excessive angle in the steering wheel (all of which will slow you down). A poly or delrin bushing would certainly reduce this impact. However, rubber bushings create less arc conflict through suspension travel as its more compliant and will exert less pull on the control arm. Installing delrin/poly only the backside and putting rubber on the front side might be an alternative to minimize braking changes but allowing less pull on control arm travel. Never tried it or modeled it, just thinking out loud.

I've thought about suing a ball joint in this position as well. You would need to weld in a sleeve to allow the mopar screw in style to live here. Other option is a chevy bolt in style. Of course you now need a threaded strut rod to bridge the gap and a solid, tapered and tapped end for the arm side.
