REAR SWAY BAR

[malibu43]

hi there ,as you know i race my 80 malibu as a road course,i need to know if the oem rear sway bar will help me in this kind of race? i allready have one,and also they need to be attached to the lower arms with the 2 bolts or could be with just one per side?
thanks

You will need 2 bolts on each side or there will be no twist applied to the sway bar.

I don't think I'd "borrow" any other ideas off any cars set up like that. Certainly not without outside review and comment.

If you're talking about a Panhard bar - which attaches to the axle at one end and to the frame at the other - that's a whole other thing entirely. For really serious cornering, you would only use that with a 3-link, torque arm, or possibly truckarm suspensions.

GNX/Kirban traction arm suspensions also use a PHB, but that's a dragstrip suspensionthat isn't a great choice for road course duty.

If you're talking about an "anti roll bar", that's a drag only part, too. Does your car understeer? If it doesn't, you don't need a rear anti sway bar (or a bigger one).

Not a great picture, but you can see the anti-roll bar on above the rear axle:

guys thanks for the replie.
but i think i did not make myself clear,the bar that am talking about ,its a bar that maybe tie the frame from side to side,that`s located almost like a rear bumper but its going under the car very close to the the end of the rails,do you got it now? if so please tell me if i do need to tie the rear frame.

malibu43,

the bar you are refering too. it goes after the rear axle.. before the bumper. i know what you mean, i think you should look at it like this. anyting you can do to stiffin the frame from lateral forces applied against it, should be applied.. i too am going for a pro touring style of my 78 malibu.

i plan on purchasing air ride tech suspension, as pro touring site gave me really good feedback from it. there mucle bars setup.
then the fender braces from a monte carlo ss. and the front support i believe it comes of a caprice.. it bolts to the front frame horns, and meets up at the "skid plate" of the front end.. think of it, as many triangles to be applied to the vehicle, add them..

and drag racing vs autocross/ road racing is completly different as far as setups are concerend.. many have told me about a man named herb adams. he wrote a book for gm chassis handleing . and as far as i remember reading, he was very infulencial with gbodys..

im not garanteeing my information is 100%, because i too am still learning.. you should subscribe to pro-touring.com,
the guys on there are very informative.

good luck with your build brotha..
