Hi John,
Rollsteer is not confined to the rear axle only .
the front axel does the same only the roll puts the axel into under steer
I will try and explain if you look at the front of the car and imagine a horizontal line going from front to back starting from were the gooseneck bolts to the spring , if the radius ball bolted to the cross member was mounted on that line, as the chassis rolls the axel would stay at a right angle to that line.
But the Ball is mounted about 4 inches below so that it moves in an arc so that if the chassis rolls to the right the ball moves to the Left and because the radius arms are attached they pull the axel back on the right hand side and forward on the left putting the axel into under steer.
This is why the front suspension is tightened to reduce roll
The only thing I would do differently is stiffen the leafs of the spring and use the dampers as dampers
but I under stand why the do it because its much quicker
I would also do the same on the rear
