SPC vs SPL for Track and Weekend Driver

loufitness

I am looking to replace the Stock Upper Control arms for Camber adjustments to achieve an optimal square track set up...while keeping the car street-able. I have researched many thread and forums...where all point to issue and concerns with SPC; however, most are older threads (2013).

Is it possible that SPC had design/manufacturing issues that may be have been corrected in recent years...or is SPC still unacceptable for track use?

I am not concerned about the extra $300...rather I am concerned about the "ride" on the street with SPL. Are the spherical SPL bushings going to be noticed (by my wife) during weekend driving?
