TR2/3/3A Contemplating TR3A suspension change

As I mentally restore the 3A I have, I've been thinking of changing out to more of a late TR4 suspension setup. This would use the TR4-6 upper ball joints, and the 3 degree castor trunnions. I think I've heard pros/cons of the conversion before, but I still like the centering/stability of the castor conversion.

I have most of these parts in dusty corners of my garage already, except for the lower trunnions. So my question is: if I stayed with 0 degrees for now, can I still use the TR4-6 upper a arms and ball joints?

Since this is at the thought process step at the moment, I am opening to objections on the idea as well!

Nope, it's a package deal. The upper A-arms move the pivot point in space, so the trunnions need to match or the whole mess will bind. The steering arms need to change as well to maintain the steering geometry (since the arm location moves somewhat as well).

Personally, I'd suggest trying it with the stock setup first. It actually centers & tracks pretty well without the caster. Many years ago (young and foolish) I drove 20 miles without touching the wheel, on the "Beeline highway". Of course it helped that that TR3A steered kind of stiff as well :laugh:

As my second year calculus prof. use to say, "that is a solution best lest for the student to derive."
