hey bb, thanks for the pic of the traction rod, though i would consider it more of a camber rod. The whiteline rear camber kit allows you to lengthen or shorten that arm.
About the laser alignment, which i use myself when i go to bridgestone, what you have posted is pretty ridiculous. I mean its not like i tighten the nuts while the numbers are changing or someones farting lol. Having done over 5 alignments my self and working progressively through alignment settings from pretty conservative to now a reasonably aggresive setting, i have no doubt in the equipment.
On the other hand i dont believe the string method to be a bad one, and might give it a shot in the future to see if there is any improvement to be had. On the other hand i pay nothing when i go to bridgestone so i might just keep doing that.
I also think the fine measurements u are talking up are not that fine, i mean say u ended up with 2.0 front neg camber RHS and 1.9 on the LHS id bet my left nut u/me whoever couldnt tell the difference.
cheers bb
