Can anyone care to explain to me the difference?

From what I've read, some say they both do the
same job. Others say, the Torsion is just a brace
to stiffen the rear suspension while the Sway Bar
is a "spring steel bar" that bends and straightens
out after an impact.

People have been saying different things but
no straight credible answer. So which one is it?

Sorry, I'm a huge noob and still learning :p

I'd like to know as well and rather than making a separate thread, I hope you don't mind if I piggyback and ask; is the "bump steer" people talk about the thing that happens when you are taking a wide turn at speed, and the cracks in the road cause the car to "hop" in a crooked, scary way? I read that a torsion bar corrects that and if so, I need one.

"Torsion bars are mounted solid to the chassis on one end and to a suspension
component on the other end. They are designed to support weight.
A sway bar
mounts both ends to suspension components and the center to the chassis.
They are designed to control body roll and do not support weight. "

"A torsion bar is a type of suspension system that takes the place of a spring.
The upper and/or lower control arms on the front of a vehicle are attached to
a bar at the pivot point. This bar runs lengthwise alongside the frame
(inside or outside) and is firmly attached at an anchor point at the other end.
When your wheels move up and down with the contours of the ground the
arms move up and down and twist the torsion bar. The torsion bar resists it
and keeps the wheel planted on the ground.


A sway bar is a different animal preventing the car from swaying by acting one
wheel on one side against the other. I didn't get into too much detail on the
sway bar because you claimed you know how they work."

almost... the front bar underneath going from strut to strut attached with endlinks is a sway bar. the STRUT bar goes on top of the strut in the engine bay.

had to bump this up because the info is not correct as far as the veloster goes. that torsion bar set up is mostly used on trucks nowadays. it's designed to replace the coil springs. this is what they are talking about on chevytalk.


it's different than what we are talking about here. from what I can see, as far as the veloster goes, they both do the same job, which is to stiffen the rear suspension on our car. I think the confusion arises because the some term "torsion bar" means different things depending on which vehicle you are talking about.

here's a torsion bar for the V:


here's the sway bar:

I just got the whiteline "torsion bar" (same thing as the Pierce rear torsion) and it's what people traditionally refer to as a sway bar. I'm guessing there's something different about the V's suspension that causes it to be referred to as torsion instead of sway.

Did it reduce the bump steer drastically?

I'm still debating whether I should get the Pierce one
or the SharkRacing Torsion.
I ordered the Whiteline version for $125 on Monday, got it today. That's $50 cheaper than the Pierce. I know the VT forum is a Pierce fanclub and will tel you that one is miles better but Pierce himself said nothing but good things about the Whiteline and basically copied their design and added 9% thickness.

Nothing wrong with supporting our vendor. I bought Pierce's. It was a personal choice and since he is on the forum pretty much everyday I can get the support I need directly through the forum.

Are you saying you never experienced
bumpsteers before your Ksports install?

I hope we're not talking about Ksport Coilovers
Or does Ksport have Torsion Bars too?

someone made a pierce comment, so i made a positive remark about my purchase of ksport coils from him.


i dont remember having bumpsteer when i was stock in either my NAV or this turbo. i put ngm springs on the NAV... the turbo is getting the coils once the snow/salt is gone.

hi guys, I am totally new to this and knows nothing about cars ... so even after searching other threads on this topic I still don't really understand entirely what the sway / torsion bar helps w/ the driving experience .. probably perhaps I have not bought a V yet and still in the process of getting one ^^|| ... so having that said, do you mind explaining in a lil more details for someone who pretty much knows nothing about cars. I drive a 1998 corolla a/t for about 10 years that i got from my parents and it's mainly just a commute cars for me. I occasionally do drive my mom's Accord which obviously I can tell the difference in power but that's about it. I do feel this sway/torison bar should enhance the driving experience in the new V that I'll be getting, do you think it's recommended for someone like me to get it installed? and if so, is that something I can just have a body shop install for me after I buy the car, or should take care of that at the dealer during my purchase?
