Does anyone have the settings for suspension geometry available. The garage I plan to use says they have obtained them but I should like to check.
They say:
For the front
toe is 3.2 +/- 1.5mm (I know this is right)
camber is 0 +/- 1.2 degres (not adjustable anyway is it?)
caster is 31.2 +/- 0.5 degrees (this one I'm not sure if I heard right)
KPI 6 degrees what is this?
For the rear
toe is 4.5mm
camber is 0.5 +/- 0.5 degrees (this seems small as the wheels have a visible camber)

Your advice will be much appreciated.

This has been discussed in the past. Try doing a search. Your visible camber might be due to bushes/UJs or lack thereof. Unless you've just rebuilt the suspension it might be worth while checking it out. Is it trailing arm or A frame?
If you get some definitive numbers then post them up please.

Jon, if you are TVRCC member, then go to the archive area and you can download the servicing manual for the front suspension which includes all the front geometry figures, And its free.

Found it, it's your post Leo, so no wonder you remember.
The garage figures agree with the Steve Heath ones so I'm happy to go with them.
The car is a trailing arm rear, I guess I will find out on Friday what the rear camber actually is.

Ahh but I have slept since then so that's my excuse
You asked about "KPI" This is King-Pin Inclination angle. It's a bit like caster(where the top and bottom ball-joints are offset fore/aft, think shopping trolley or bicycle) except the top and bottom ball-joints are offset inboard/outboard. In other words the steering axis is offset from vertical but on a plain perpendicular to that described by caster.

I have a great deal of respect for people who can explain a complex idea using simple terms. My forte is to be able to explain a simple idea in a way that makes it seem more complex.
