Lowering a 91 LX

I have a set of Steeda springs that came witht he car when I bought it and was wondering what new components I would also need to get before installing the springs so that my alignment doesn't get too screwed up as well as recommended brands/compaines to purchase said hardware from.
 
Caster Camber plates. I have used FRPP and BBK ones. Both worked great. If u have steeda, might as well put steed cc plates on. If u want to get real craft u can add new struts and shocks since u have to get a new alignment anyway. While ur at it, u might as well add new poly bushings to the front susp and maybe offset rack bushings to help with bump steer.
 
Here's what should be on the must do list:
Energy suspension isolators all the way around the car.
ES end links for the front

I'd suggest the CC plates, but i had bad experience with my BBK's.
Maximum motorsports CC plates are the best, and they cost about the same as others so...

Don't mess with Control arm busings up front, if your ball joints are shot or the front a arms need bushings buy the ford racing set of arms which comes with both.

As far as rack bushings, the verdict is still out, i have aluminum offset rack bushings, i really can't say for sure if they actually help.

Since you will need an alignent, check all tie rods.
 
The car has new shocks and struts that should have less thant 5000 miles(not sure of an actual number) and there isn't anything wrong with the suspension if that makes a difference.

[Energy suspension isolators all the way around the car.
ES end links for the front] What will this do?

Increases your ride quality. Keeps your suspension from going metal on metal.
The stock ones get flat, torn, dry rotted.
People have a habit of just removing them during a spring swap.
Been there done that, and i assure you, it's a bad idea.
