off set upper control arm bushings worth it???

well when i take the car into the tire shop for alignment
will they use specs from factory call out???
this is a GOOD friend of mine so if i tell him i have them bushings im sure he can go to the max use of them
will a normal guy like me who just drives the car around and on high way even notice a difference with cornering and steering
i know my car sucked at them before i tore it apart alignment was way off and bushings blown out
