Roll Center

Has anyone actually measured the roll center and CG heights (either stock or lowered)?

Thought it might be worth checking before I go measure myself.

I assume roll center is the balance point of the car from the front to the back and the CG is the center of gravity from the ground to the roof. is that correct?

How would you go about measuring either of those?

But I think it's worth checking yourself.

Simply put, it is the point, or axis, that the car rolls around, when cornering. It gets more complicated, once you put dynamics into it, and the roll center starts to migrate.


Some suspension engineers design around it, others nearly ignore it. I've worked with both.
