Are there lowering springs on a Lincoln Mark VII?

there is a coil spring conversion made by Arnott, i have it on my 91 LSC SE and the ride is so much better, i would check out Eibach, Tein, and other spring companies, as well as cross reference parts from a thunderbird/cougar/mustang of the same year range There are ride height adjusters under the front and rear of the car to lower the car all you need to do is adjust these and you can drop it at least a couple inches. only make sure car is supported by jack stands when doing so.
