    time to replace rear suspension on 11.60 drag car, the problem is these springs are for optimum squat, these control arms are for maximum lift, those shocks adjust 10 different ways, these bars are fully adjustable, those you need to put in braces...

    I'm thinkin adjustable uppers, tubular lowers, moroso rear springs, 50/50 lakewood shocks... ? limited budget HELP what to do ?

    whatever you do get a spohn or hr bar on the rear. and get the lowers that are longer than stock. and adjustable uppers. or better yet. back half it and 4 link it as long as you do the work yourself its not too much. just WORK! and tons of it.

    Nothing wrong with the A body's suspension. NO reason to go hacking one up! Talk with a tech to help choose the correct weight of spring. Adjustable uppers will help get the instant center, boxing the lowers will be a conservitave fix till your ready to splurge and buy adjustable's. A good quallity anti roll bar is the best thing to do. It'll make the rear plant on a gravel road! Hope this helps? :TU: John W.

    is your car hooking good now? Or are you trying to improve?

    For an 11.60 car, I would use stock rear replacement springs with an airbag on right side. Stock sway bar and cheap 50/50 shocks. And change up the front for weight transfer.

    :idea2:
    Consider Jegs adjustable uppers and lowers, stock cargo springs, no hop bars, and HR Parts & Stuff sway bar if the car twist up.
    This is the set up I have and I consistently 60 foot between 1.36 and 1.41 (at 3788 LBS) and pulls the front end about 11/2 feet on the foot break. measure angle at engine dampner and set pinion to same angle.
    Torque converter flashs about 400 above peak torque.
    This year I am putting and Elf Weibe suspension in it, hope I don't drag the bumper on the ground!!!

    Just today finished up installing an HR Parts & Stuff swaybar. Took the car out for a test drive. It drives like a completely different car . A drastic improvement in handling. Now I will take it to the track next year and see how much of an improvement it made on my sixty foot. John. :pray: The HR Parts & Stuff Bar is a worth while investment to improving your sixty foot and overall handling.

    Another trick instead of the airbag you can put an el camino spring on the right side

    The air bag is for the track and you can let the air out for the street, unless this is track only..


    What is your weight, 60', and rear set up before the mods?
