I spoke with an old hot rodder/racer about this the other day about this and he said the uppers see so much force under breaking that it would probably shift. My uncle was a front end mechanic for chevy for 30 years. I told him what I was doing and the upper arm shaft idea and he suggested to fine tune the uppers he would unbolt the shaft from the studs and twist it. He said he used to do it all the time and each turn on the shaft is just under 1/4" forward or backwards off the top of his head.
