I think thats the right termanology for that 3-4 inch thick circular bar that is bolted to the cars subframe right in front of the rear tires. The reason i ask how strong it is is im planning on figuring out how to set my car up with a rear sway bar and am thinking through ideas in my head and one of them involved throwing U bolts over the tortion bar and bolting the sway bar to it. What do you all think of that? Good idea or suicide?

Sweet Cobcob. Thanks for the link. Now that i see it i remember that from awhile ago. I dont see why i couldnt find something similar at a junkyard and make it work.

I aim to please!!

I think after looking at that rear sway bar and looking under my car im going to attempt to make my own out of 7/8 inch (maybe smaller) round stock from home cheapo or something like that. Bend it to the right shape, flatten the ends, drill two holes and bam..done. Ill let everyone know how it turns out.

Anti-sway bars are made out of spring steel and heat treated. You'll have to get that material from a specialized vendor and heat treat it after you form it.

 

If you use mild steel it will soon crack and fail.

omg!!! i want that soo much, lol.

 

anyone know what that kit runs as far as price and availability?

I looked on ebay and anything from that company was in the 175 dollar range so im assuming around there.

An EA82 Turbo rear sway bar is much easier and cleaner to install - you just have to cut the brackets off the EA82 trailing arms and weld them to the EA81 arms. The ends of the sway bar have to be shortened slightly as well - a band saw would be best. Qman did that with his dark grey Brat IIRC.

 

They mount ONLY to the arms so fitment is much easier as there is no modifications to the torsion bar tube.

i wasnt planning on modifying the tortion tube. I was just going to put a u bolts over it and bolt the sway bar to it. If i could find a EA82 turbo around i would but here in new england they dont grow on trees :-\

i wasnt planning on modifying the tortion tube.

 

Yeah - that won't hurt it any.

 

Still - put up a wanted post for an EA82 sway - people are always upgrading the OEM's on their RX's and such with the XT6 version.... shouldn't be too hard to find one.

 

GD

Hmmmm XT6 you say....oh connie .

GD i have a question for you about sway bars. If the EA82T and the XT6 bars dont mount to the frame at all, how do they do there job well? Isnt the point of mounting them to the frame to keep the rear from..well...swaying? Wont it sway with the bar just connected between the trailer arms?

Bump for ^ question.

Bump for ^ question.

 

The bar is connected to two points on each arm rather than the conventional arrangment of one point on each arm and two points on the body.

 

Actually the point of the sway bar is to limit the amount of difference in the travel of the two arms. If one goes up the sway forces the other one to match - and so forth. This keeps the car from tilting as the only way that can happen is if one arm is up and the other one down. Going into a corner the outside arm will compress and the inside will extend. The sway bar causes the outside arm to exert a compression force on the inside, and the inside exerts a pulling force on the outside. The bigger the bar the more it tends to keep them level with each other.

 

GD

dont think the frame has anything to do with it exactly. The sway bar resists one wheel moving up/down opposite the other wheel via torsional (twisting) stiffness. whatever its mounted to to keep it from flopping around is irrelevant.

the torsion beam does the job of a sway bar...

 

what you want is to strengthen the beam between the arms..

 

does it unbolt? so you can bolt in something heavier?

the tortion beam doesnt really do that cause its not connected to the trailer arms so one side can sag down more than the other going into a turn. Im trying to get my car to handle flatter.

Hmmmm XT6 you say....oh connie .

 

We talked via chat room yesterday..you know if we can get it off..its yours.

 

I want to follow this abit too cause I may want to do something similar to my coupe

Well connie you already have the sway bar now so if you want it when we go to pull stuff off thats fine too..since it is already yours.

the torsion beam does the job of a sway bar...

 

No - it doesn't. The torsion bars themselves (inside the tube) are independant. There's a seperate bar for each trailing arm. They have nothing to do with each other. That's why it's called "independant suspension"

 

GD

then it isn't a torsion beam suspension.

 

it's an independant rear suspension.

 

if you have your terms wrong to start with how can you expect a good answer.

 

(see I can be an rump roast too. and I went out on a limb for that I really thought when you all said torsion beam it was an actual torsion beam suspension)

 

does it have springs, too? or dio the bars act as the springs?

My original post should have read "the beam acts as a sway bar?"

I see where I goofed... I stated as fact when I meant to ask a question

 

my bad!

No one said anything about a beam style suspension. What we said was torsion "TUBE". The bars are encapsulated in a single tube.

 

And no - it doesn't have springs. That's what the torsion bars are for. It has external shocks and an internal (adjustable on the 4WD's) torsion bar assembly.
