1989-1997 Thunderbirds/Cougars came from the factory with Progressive Rate Coil Springs..
Progressive Rate Coil Springs do intentionally touch one or more coils to reduce the number of active coils and increase the rate..
Progressive Rate Coil Springs deflect at different amounts per inch. An example would be: 300 lbs. = 1 inch deflection, 700 lbs. = 2 inch deflection, 1100 lbs. = 3 inch deflection, and so on.
Progressive Rate Coil Springs have a soft initial spring rate, and a much firmer spring rate to handle more weight, decrease sway, and improve handling.
All Progressive Rate Coil Springs...Factory(stock) or aftermarket will always be installed with the "tighter coils" on the top..
Some aftermarket lowering springs are installed differently..
Please contact the Manufacturer of those aftermarket lowering springs..If you are unsure about which way they should be installed..
