The camber change when cornering is compensated by the change brought about due to the castor angle. ......that is all part of the calculations in designing the suspension.

Camber change from lock to lock is really small and under static conditions largely irrelevant as the camber change in roll when cornering is much bigger and therefore much more of an issue.
BTW your link does not explain any of this.
Camber recovery systems help to keep camber change to a minimum under all dynamic conditions and is great on a race car in the wet but a pain in the butt to set up in the dry.

As i understand it only a car with zero castor will not show a change in camber on turning. its a well documented phenomenon. since you profess some racing background perhaps this link will provide some useful info

a car with zero castor would be unpleasant and /or unsafe to drive.
of the 4 duttons i have had geometry checked they all had between 5-8° castor so some camber change will be evident on turning the steering wheel.

Really Dave!
Camber changer when turning the steering wheel? Maybe you Andy Scan explain.
As for TDW's steering design, early cars just used an OEM design and the later cars he had someone do the design.
If the wheel base is different side to side that's more likely to be down to who made the chassis rather than design.

It is normal for car to exhibit camber change when steering it has nothing to do with tim‘s chassis design. ALL CARS DO THIS to some extent or other. it is often more pronounced on cars with large castor angles. as i say it is all compromise.

What else could cause it other than castor or anti squat, which I don't think you could do on a leg?

I just thought, the lower measurements on the passenger side could be down to the big ass toolbox sitting behind the passenger seat too.

You can clearly see the discrepancy in the front n/s wheel arch too.

Those pictures are a bit better for me, Adrian. So I have done the measurements for these two and these are the results. Note that the latest pictures are quite a bit bigger so they should be more accurate.

	Side	Front	Rear	Clearance
Adrian's Earlier	Right	6.8"	9.0"	1.7"
Adrian's Latest	Right	6.4"	8.4"	1.5"
Adrian's Earlier	Left	6.7"	7.9"	1.6"
Adrian's Latest	Left	6.9"	8.2"	1.7"

This is now going to be a bit picture intensive...

O/S

 

 

 N/S

 

O/S FULL LOCK CAMBER

 

AND FROM REAR

 

N/S FROM REAR

 

AND FROM FRONT

 

FRONT ...The difference between wheel angles in not exagerated by the camera, they really do deviate that far.
