SS/B Barracuda project

I shall express myself more clearly, and want to start with what effect the spacers have on the front suspension, e.i. stability and handling of the car. If the spacers means I have to tamper with the upper and lower control arm as well as the lower steering arm, I have to pass on the use of the spacers, as I have plans to get the traffic techs approvals, and use the car on the street, at least occasionally, witch in reality probably will mean a number of hours ;)

????Question: Do I have to adjust/bend upper and lower control arm, as well as lower steering arm, or any of them, if I use ½" spacers????

This question is crucial as to how I move on. No room for assumptions here. Sense it also is a question of safety.
