Not to stir the pot, but personally I think the manual is ok on steering geometry versus having link 90 deg to servo because the link is not 90 deg on the steering upright.
Manual seems symmetric and looks better. 3rd place car at the Tamiya worlds a few years ago.
Mine is actually at 90deg to servo horn link primarily because that is where my radio trim is at perfect 0, and I do not want to have +30 on the trim just to get the servo to the above position (as it starts to have a weird effect on the epa of the servo).
