The M3W suspension in standard form is far from perfect and requires the Empire kit or similar modifications to get even close to your diagram. With it fitted Line 2 is achieved, as well as adjusting caster and camber. The Comfort Kit addressed some of the bad design and reduced the bump steer. All it did was raise the steering arms to a horizontal position and this seems to reduce the bump steer to an acceptable level, later cars had the Comfort Kit built in with raised steering arms on the uprights. In practise a horizontal steering arm, with a standard comfort kit set up, seems to be the best compromise. Although the standard suspension is non adjustable there are some quite large variations, even from side to side, particularly with early cars.
