Advice needed for modification

dont waste your time do an alignment put more positive castor in front and more positive camber in rear

The Alignment is fine, no problems there - the tires are not wearing out unevenly and the car tracks perfectly fine on the straightaway. It can go down the highway at high speeds staying in a straight line without the need to hold on to the steering wheel. (not that I drive without holding the steering wheel)

you are a TARD i set ya up for oversteer you are a TARD

You already have a front roll bar/anti-sway bar.

First step... get the rear anti-sway bar & hardware from a 96-99 SHO and install that first... it will instill less understeer.

Install urethane bushings in place of the rubber ones.

Get sticky HP tires... at the cost of longevity.

There are shocks & struts available as upgrades. Variable rate "cargo-coils" for the rear. How far do you want to go?

Check some of the Taurus/Sable enthusiast sites for further details.

Positive camber for cornering ability???

Unfortunately, those settings that improve cornering ability usually sacrifice straight line stability to some extent (oh, I can see you turning those words sideways). Toe out can make a car wander but do improve it's ability to "turn in". Negative camber has the outside tires set for cornering. Suspension deflection on hard cornering can induce toe change in the rear suspension.... this is an area deserving some research..... research - not cut and paste.
