Never had a problem with the ackerman on the 68 Dart, it was done right! Backed up and turned the proper way (no outside wheel turning more than the inside) pinto rack, 74 Dart k-frame, lower ball joints swapped side to side. More info will cost ya.


We agree then, there is a difference between "sacrificed proper Ackerman" and "never had a problem" ?

For those on the sidelines who might be scratching their heads here, normal Ackerman in a front steering two axle vehicle, is defined as the intersection lines drawn thru the outer steering tie rod ends thru the lower balljoints to the center of the rear axle. It is assumed those lines are mirror image on the centerline of the car, when the front wheels are pointed straight ahead.
Those lines need to be same angle whether tie rods are in front or rear of the front axle line.
Meaning, the tie rods are closer on a rear rack IFS, and farther apart on a front rack car.
That can't be changed significantly for proper Ackerman, period.
Ackerman effect becomes more significate the smaller the turning radius.


A picture is worth a thousand words
