1979 malibu landau

[74dodge]

hey guys im new to the site i recently picked up a 1979 malibu and want to go for more of a pro touring look i want to be able to show the neighbourhood rice burners that american cars can take corners lol so i was wondering what the cheapest way to stiffen up the suspension and lower it would be?ive been doing some research and supposably you can take the front springs off iroc camaros and put them on same with the front sway bar but what about the rear what can i do to stiffen up the rear end?what about shocks would i have to change them?supposably if you do the iroc suspension it will drop the car 1-1.5inchs is any of this true?are there any other cheaper ways of stiffing this up and remember i will be buying used enlse new is really cheap haha
