The steering arms is the other aspect to consider - depends on who you ask. Generally bump steer is defined as the tendency for the vehicle wheels to steer (toe out/in) upon suspension bound.
But the way I see it, bump steer will occur over two circumstances -
* Alteration of track - as the control arms move upward, the track of the vehicle decreases [ie the wheels move *inwards* towards the car]. This can bounce the vehicle to the left or right depending on which wheel (on the same axle) has more load on it at the time.
* Alteration of length of steering arms - as suspension bounds, the effective length that the steering rods need to be to maintain zero toe changes.
Another way to change steering arm angles is to use rose jointed tie rods spaced downwards from the hub knuckle as opposed to spacing the whole rack up. But however, like the above method of dropping ball joints - will place extra strain on the joint. Heres an example -
This is something i've considered for a while - I'm surprised to not have found any information on this forum about it - some of you guys have super low cars!
