Suspension recommendation 1972 Torino Sport

something like,

replace worn parts (steering links, ball joints)

cut crown vic springs (to adjust ride height to taste)

poly bushings on the control arms

rubber bushing on the radius rods

Bilstein shocks (crown vic fitment maybe???)

max out the caster

camber and toe to factory spec

there is some steering gearbox stuff you can do, search around the forum for that

obviously good tires all around

If you are trying to improve handling to good street performance handling and are okay with a firm ride, the following works well.  Start with Crown Victoria Police Interceptor cars springs, Moog 80090 in the front, a rear spring with about 160 in/lbs, a decent set of shocks (Bilstein or KYB), new bushings, and Addco front and rear sway bars.  This will make a big improvement in handling, especially if your car has base level (read super soft bad handling) suspension.  Next the steering box needs to be upgraded.  I receommend swapping to a Saginaw steering box from a 1971 Mustang, and have it built with 12.7:1 gears and high road feel for quick steering with maximum road feel.  The Moog 80090 are hard to find, but you can get the Husky equivalent from RockAuto:
