DC/MD/VA - Original Flyin' Miata 90-97 springs
These are the original (lower) FM springs. Still in decent condition, no squeaks or sagging. These put my porky 97M around 12" front, 12.5" rear. $150 shipped to the lower 48.
wow, a bit higher mileage than i wanted. but the girlfriend is willing to pay what i put in the PM as a gift for me. haha. if ur okay with it, just PM me back with an answer.
im usually on between 8am - 1pm while im bored in school.

Trust me...the mileage on these doesn't matter.
It's a matter of fatigue stress design in springs.

In the above the y-axis is the stress in the metal coil of the spring, and the x-axis is the number of cycles to failure. You'll notice the curves for the material (ferrous one on top interests us here) approach a lower limit as expeted stress decreases.
A well designed spring will never see stresses near this limit, and therefore never have appreciable fatigue that would require fatigue life calculations. Airplane trusses have a fatigue life...automobile springs don't.
