I used '99 Mustang springs in mine. My Bird is an '88, but would work the same in your car.

I have fox mustang Steeda springs in the front and turbo coupe Moog replacement springs with a couple coils cut off in the rear.  Also have Fox Mustang shocks/struts with Chuck W shock adapters in the rear and Fox Mustang spindles up front.

What is wrong with cutting the original springs and setting the height to your liking. Dont get me wrong i change many springs in my career but cutting is a viable option. have a great night guys

^^Cutting springs will lower the car. But with lowering springs you can get stiffer springs. You can get progressive spring rates or constant spring rates. I noticed that my car dives A LOT LESS under braking with stiffer springs

2000 GT front, 1999 V6 convertible rear.  At this height, the car looks right.  My roof line is visibly lower than that of my wife's 2012 Fusion.

But cutting the springs does change the spring rate as it is a function of coil diameter, number of coils, and thickness of the steel used to make the coil.

**SpringRate = (Thickness)/(nCoils*CoilDiameter)

So with all things being equal reducing nCoils increases ones spring rate, so yippee!

Removing effective coils  increases a springs  rate as explained above. Cutting springs is totally acceptable and done all the time. have a great evening guys
