Remember the stub axle isnt at 90 degrees to the kingpin...
Simon @ SiFab.co.uk
I know, in theory it is 91.5 degrees if the camber is 0.5 degrees negative and the kingpin inclination is 2 degrees.
However, it is the kingpin inclination that determines the sideways bump movement and it is this angle relative to the track rod angle that affects bump and roll steer. I will get round to measuring it again but I would have sworn it was about 2 degrees, hence the bump or roll steer tendency with the track rods at about 4 degrees.
And the more it rolls the more pronounced the steering effect which is why I readjusted the spring seat height to minimise it.
Of course I could be wrong so you can explain where my thinking is going awry if you've got nothing better to do at Race Retro.
PS... If you remember, would you take my Panhard Rod to the show. Not sure which day yet.
