This thread has every design of becoming something like: "how it took 10 visits and $2000 to get an alignment"
But seriously, Val, 5hrs to do an alignment, even by "traditional means" is just a wee bit absurd.
I think your guy is proly bored and really likes your company. And likely will seek more of your attention as time progresses. Or maybe he will simply empty your wallet...Obviously i have not a clue. Except that he is not going about it the most expeditious way.
GM has published proper specs: use them with one exception: max out F camber. That's it. Everyone here has been doing it since the gen6 came out. There is no wheel to get reinvented. Simple. Everything else is just theoritical musings and a pile of horse $hit regardless of how much experience one may have. Unless your suspension is broken, which is a completely different subject.
Ive had my own experience with an aged Hall of Fame star, which turned truly bizarre. But i wont share its details, as they are unrelated. Except that somebody's past is not always relevant to the present, or future.
A proper alignment is not rocket science. It is up to you to make the process simple. But, if you enjoy those visits and lool forward to many more, then that's a completely different subject now
Cheers!
