Wow, much appreciated Tony! I was hoping you might be able to help in another way however :)
I don't think they are able to do "full" geometry where I'm getting the work done, they are certain the castor angle is not adjustable on the IS200, and it must be because of course your settings change it. I asked them about castor and KPI off your settings because I figured out they are the things that very few places they can do, and they pretty much confirmed they can't do that stuff.
So...
I'm going to ask them to get the wheel aligned as best they can once that bent bracket is replaced (so at least the camber and toe will be fine) and make the car safe, and them could I bring the car to you please to get it finished off properly?
By the way, you mentioned the tie rod, is that the piece that goes from the wheel towards the back of the arch, with a bend in it? They wanted to replace that item too, but he found out today that is £125+VAT, so he's going to try just doing the bracket first. With the bend in that piece, it's impossible to tell whether it's bent from looking at it!
Yep the Tie-rod is the longitudinal rod the goes from the lower wishbone to the chassis, it's job is to control the castor position that's why i feel it may be bent...... saying that at that cost the bracket is a wise move first.
The KPI, Castor and some other angles on the IS200 are used for diagnostics to triangulate where the bend/s are, most Geo machines can measure these angles but few places use them simply because the information is difficult to analyze.
They are correct in saying the castor's not adjustable (directly)..... To explain, the suspension and it's sub-systems are not built at right angles to each other. When i Math the tyre wear issue with the Lex years ago i found the problem was the low castor position on the corner generating the wear, so the goal was to move the adjustable camber which in turn massively violated the toe which in turn when corrected/moved the castor forward :)
