511 Steering Geometry

[djmcnz]

So I'm doing a screw-by-screw rebuild of my 511 at the moment out of necessity rather than desire and in doing so I got to playing with the steering and wondered about options.

I'm not a geometry whiz so don't really know what maths is involved here but look at the pic below, wouldn't the left side (of the pic) labeled "Mod" be more efficient?

I think the Ackerman would remain the same (no change in pivot points) only the steering rods would get shorter.

Wouldn't this provide more 'direct' steering with less throw required for full lock? May require adjustments to steering Arc/Expo but that's easy enough.

Can anyone far smarter than me tell me why one is better than the other? The 'mod' certainly looks more elegant...



Thoughts?
