School me - replace upper ball joint with heim joint

That's fine in a straight line.

Now what happens when you corner.

The body leans, outside tyre is taking the load, and the car is leaning on the outside edge of the tyre, instead of the maximum about of tread that we could have on the road.

The camber would not change if the arms were of equal length, but unequal length arms have different pivot centers around their specific radius, hence the camber would change.

Leroy, can I ask if you have checked the actual geometry of your current set up to validate that there is an issue, as you really need to check to see if there is a problem with this set up before you change it and potentially make it worse, not better..

You could well be making the geometry worse rather than better.
Just going back to basics, if your uppers and lowers were of the same length and remained parallel during up/down movement, then when cornering, your wheels would remain parallel to the centre plane of the car, and the wheels/tyres would be at an unacceptable angle to the road (because of the roll of the vehicle). Hence in a 'simple' double wishbone setup, there are significant deviations to the arm geometry and mounting points to achieve a better compromise....so back to the comment that you would probably be making the situation significantly worse.

Cheers,

Yes, agree.

There are many variables as to amount of camber change during wheel travel.
