That's what I mean though... If you don't put the locating pins in, and unscrew everything (now the subframe is floating), then you 'just'
need to place the consoles properly (e.g. audi dealer?), and the subframe will end up in the place it's supposed to be in once you screw it all back together... no? My reasoning is that what you really care about is wheel (and therefore console) position relative to the car chassis, and the subframe just follows. The steering rack obviously also has to be aligned perfectly at right angles to the longitudinal axis of the car.
Basically, I reason that the subframe alignment doesn't matter because the wheels are connected to the wishbones, which are connected to the consoles, and while those are connected to the subframe, they are also directly connected to the car (is this not true?), and the latter is what matters for geometry?
Still no cigar?
Maybe I should look under the car before theorizing, lol.
