You want a smooth ride, but good steering response?

-Factory coils (reuse existing)
-Soft gas shocks (such as KYB GR2 or Monroe replacements)
-GlobalWest (GW) Delrin control arm bushings on stock arms (upper and lower). Also check Detroit Speed (DSE) or SpeedTech Performance.
-Hotchkis 1.125 hollow sway bar
-GW, DSE or SpeedTech solid tie rod adjusters (as opposed to factory)
-Fast ratio pitman arm
-Aluminum body bushings
-Whatever is left can be rubber (bumpstops, etc.)
-Radial tires
- Alignment (radial tires only)
3-4° Caster
1/4 to 1/2° negative camber
1/16 to 1/8" toe-in

I've heard from others who have used them, that solid control arm bushings with nylon inserts actually make the ride smoother since the "zero deflection" allows the spring and shocks to provide more of the damping (which is why they are there).

In my own experience solid body bushings with a stock suspension did not degrade ride quality (but oh what a difference in handling).

The larger sway bar will stiffen the ride a little but no where near as much as stiffer springs would have.

Stock tie-rods (look at them as you'll see why) tend to deflect more, making the steering feel sloppy.

Radial tires were fairly new on the scene when these cars were built, so the factory settings are designed around bias-ply. Not optimal for radials.

Fast ratio arm is slightly longer thus making the effective steering ratio slightly faster without changing the box.

I'm no expert, just collecting information from several sources over the past couple years. I'm in the process of doing all of the above to mine, but it's not finished yet.
