Follow up on the braking wobble: my car wobbles when braking softly when about 50mph (80kph). I can get a very subtle wobble when steering past the center (most obvious when making slow lane changes). In my experience this is always the ball joint in the control arm. (Not the thrust arm).

Hard braking will force a loose ball joint into a locked position so the wobble goes away. Also the frequency of the wobble is not speed related.

Wobble frequency changes with speed and stronger when faster and pronounced when braking firmly it's always the rotors in my experience. (A previous car of mine was Z28 Camaro and I had plenty of experience with rotor shake with that car due to some heavy brake use: I've had the rotors hot enough you could feel the heat like a campfire when you walked past.
