Well, yeah, we KNOW that...
We are talking about the easiest way to make that small improvement!
I don't know what your calculations say, but mine (done along time ago
with a PASCAL program) says the way to FIX the ackerman angles
is to move the rack back under the engine in a "rear steer" configuration :)
