I have seen sway bars. Not really sure what does it do.
I did some research but none of the topics about the size.
I have seen 18mm, 19mm 21mm.
What are those numbers for?

What would i benefit from it?

How much are those usually run? (i have seen all kinds of price on those bars)

The Rear sway bar connects the 2 rear wheels together. What it does is limit the ammount of body roll on the rear of the car. This helps keep the wheels better planted on the ground. You can adjust the setting on most bars for the ammount of under or over steer that you wish. The tighter the more over steer.

The size also determines the stiffness of it as well. where 17mm is less still in most cases then 19mm. Most of the 21mm are hollow or tubular causing the need for the larger diamater for the same stiffness. But it has an over all lighter weight.

Most people are selling the rear sway bar for about 200 dollars. Right now we have the eiback kit on our site which includes the front and rear sway bar for 299.

The eibach is a dual adjustable 19mm read and a 25 mm front bar.

E-Mail me if you have any questions.

thanks for the info!

I was having a hard time to understand the info you gave.

I'm not a pro and nowhere near a pro, so i just gotta have to live with my beginner life.

It seems sway bar will help a lot in the course. It does not help anything in daily driving, right?

I might consider it after i got the pulley done.

Do you enderstand the concepts of oversteer and under steer?

The sway bar will make dailt driving a bit harsher, but not by much. They will make driving a bit more "fun" though. If you have questions, let me know and I will do the best I can to answer them.

chrisfb1,

The rear sway bar is a suspension upgrade. If you have a cooper with sports suspension plus (SS+) then you don't really need to add the rear swaybar.
Look on your dealer invoice for the SS+.

If you only do street driving and don't turn on corners really hard then a swaybar isn't going to help you much.

If you are thinking about a pulley upgrade then you have a Cooper S. An upgrade for that would be a 22mm rear swaybar by Madness, H-sport or RDR.

Usually you do not need to upgrade the front swaybar since it is adequate already for most owners.

The smaller diameter swaybars like the 19mm bar is for Cooper owners that don't want as stiff a bar as the 22mm one that Cooper S owners use. Too stiff a bar isn't helpful. Most bars have 2 or 3 holes to adjust the stiffness of the bar for your suspension. Usually using the middle hole is a good place to start and then drive to see how the car handles for you.

Off hand if you car steers OK with the way you drive now then you don't need to add a rear swaybar. Adding a rear swaybar would reduce or minimize understeer in the rear and give you better control of the car when turning fast. The bar doesn't help you going straight.

>>It seems sway bar will help a lot in the course. It does not help anything in daily driving, right?
Correct- daily driving isn't helped much by having a rear swaybar.

>>I might consider it after i got the pulley done.
You can add a pulley if you have a Cooper S.

Understeer is when you are in a turn, and the car does not turn (or pushes) Over steer is when you go into a turn, but the backend slide out from the axis of the turn

Neutral is when the car stay's on the axis or the turn.

Most cars are set up to understeer from the factory for safty reasons.

People like a little bit of oversteer as it can help you in a turn under the right conditions.

Somewhere in the past I read the differences described this way:

If you hit the wall front end first, it was understeer.
If you hit the wall rear end first, it was oversteer.

I actually just picked up a new rear sway bar that UUC just recieved. I will be testing this soon, and will report back. It's a dual adjustable, and the price is very good. I will get some pics, and post results later on.
