Front end alignment....Mapping the way the numbers move during suspension travel
Now let's look at the numbers for the B-F-M-J-R knuckle/spindle.
At ride height and zero camber, the later spindle gets a little more caster at 1.31 degrees.
This spindle has a greater amount of toe change during suspension travel. Note that at 1.5 degrees of dive, this spindle loses much more toe in than the A spindle.... .052 of it. This would be an instance where an alignment after ride height would be smart.
One thing that also matters is caster gain and camber gain as the suspension compresses. The A spindle goes to 1.22 degrees of NEGative camber at 2 1/4" of dive. The BFMJR goes to 1.69.
The A spindle has a caster of 4.89 degrees at 2 1/4" of dive. The BFMJR has 4.77 degrees.
What I noticed was that the A spindle showed less TOE change in the range of travel.
I was amazed at how much the caster and camber changed though.
