I'm sorry, I don't have an answer for you.
I am curious why you would want to use a 650 arm though? Is there something special about a 650 arm vs a 550 arm?

s650 replace front control arm from Steel to Aluminium. It should be lighter, and maybe better. My current Stang`s stock one got 10 years old now. I`m thinking if the new one works or not.

It saves a couple of pounds, still need to install spherical bearings in the arms to eliminate the caster changes. Yes the 2022 knuckles have better steering geometry, and a stiffer hub.
What is "better" about it?

The Knuckles on March 1, 2021+ later builds utilize a longer steering arm that improves steering geometry, gives more leverage to the steering system for higher loads, the bearing is also much larger with more surface area, the knuckle itself is also more robust. Everything is improved over the prior generation mag-ride knuckles.

I knew this about the recent MY builds. But I put GT350 brakes on my GT so I need to lay in this new bed that I built going forward.

I guess I still don't understand what is better about the geometry. I can visualize a different camber gain geometry, but not for anything involving steering. Maybe a shorter offset between the arm ends?

Duh, I turn the wheel and my car steers, haha.
