Help With Choosing Replacement Coil Springs.

Howdy StangNet,

My coil springs have now reached a point that they sag and cause the car to list to one side, and I need to replace them. Here is a list of chassis and suspension mods to better understand the current level of the vehicle.

89 LX 5.0 Vert:
Kenny Brown: Strut tower brace, K-member brace, and subframe connectors
Maximum Motorsports: Camber-Caster Plates
95 spindles and brakes up front
5-lug drum out back
17X8 Tri bar 95 wheels wrapped in 245/45R17s
Polyurethane front control arm, and sway bar bushings
Tokico Blue Struts and shocks
Fresh new Rack & Pinion
Rear arms are completely stock with rubber on both ends
Stock front and rear sway bars

I do not go to the track (drag or road course). I would prefer not to drop the car an inch or two with aftermarket springs because of the larger tire/wheel combo and smaller wheel wells. I subscribe to the notion that a softer suspension and stiffer sway-bars give a better ride while still providing the ability for a spirited drive. Such as was done with the 93 Cobra. Part of me wants to go with stock 5.0 front springs front and then go with 4-cyl convertible rears. Im also thinking of using the Steeda X2 balljoints to get a slight drop with the stock springs.

So, what are your suggestions, StangNet?

I forgot to mention that the vehicle has about 240K on the odometer. I'm currently having fitment issues with the wheel tire combo I have choose need to add limiters to my rack also. This is one of the reasons why I would prefer to drop it at most a half an inch which is what i thought my suggested setup would do.
