Quote: I looked and could not find the chart I saw. It showed the tall spindles toe change almost identical to the short one. I do agree camber change will change toe. Camber will change unless both upper and lower control arms are the same length. That's not going to happen. Doug
Caster change in bump and rebound has a large effect on bump steer too. Looking at the side of the spindle in bump and rebound, the spindle rotates forward and back. That moves the lower tie rod end up and down and changes bump steer.
A lot of that comes from the side angle of the upper control that is made for anti dive. That's why Hotchkis relocated the upper control arms on thier B/E body arms to take some anti dive out (not fully remove) and reduce bump steer.
Steve’s right. We did change the location of the upper control arm pivot point for anti-dive and bump steer correction. Toe change during suspension compression and rebound makes a car less fun to drive hard and uncontrollable understeer when the toe change is severe enough.
We put this cool little video about the bump steer change with the Hotchkis TVS for the B and E bodies.
