Looks like what a lot of drag racers did in the 70's .
the downside being
reverse ackerman when using the factor steeming arims pointing forward....but they made very limited turns
extreme bumpsteer.....but the Pro Stock guys limited suspension travel to nothing. Joe Pappas explained to me that they ran the Mopar Missile on the stops.......no suspension travel except the deflection of the rubber stops.
Good luck, I have some experience with rack and pinion installs...PM or call me if you want
