911 is ~3 turns lock to lock, non assisted
964 is ~2.81 turns lock to lock, assisted
993 & 993GT2EVO is ~2.47 turns lock to lock assisted
993RS 2.73 assisted
964 manual ~2.6

Actual steering ratios, again factory specs, higher# = slower
964 18.48 slowest
993RS 18.25
993 16.48 fastest

As you can see in the picture, the distance between the center of the holes on each one of the uprights is exactly the same. One curves left to right, the other right to left, to accommodate for lower arm while retaining the same distance to the pivot point. This causes the optical illusion that you are probably seeing.
