factory spring dimensions?

[M-Sport fan]

Has anyone actually measured the uninstalled free HEIGHT, and outside diameters of both the front and rear factory stock springs for this car?!
I have the spring rates, but want the other dimensions so that i could try and find an off the shelf, MUCH HIGHER linear rate, but ~0.5" lower static ride height spring in the Hyperco catalog to pair with Bilstein B6es (IF the rears EVER become available again).

Also, are these pigtail on BOTH ends, front and back, or is one side ground flat?

Thanks in advance.

By uninstalled do you mean off the damper or will on the damper but off the car work?
