Hi a friend of mine has some eibach anti rol bars for sale, and im just wondering if they are any good?

Do they improve anything??

I dont really know to much about them. :confused:

Thankyou in advance

Anti roll bar (ARB), stabilizer bar, sway bar all basically the same thing. It basically helps keep the car flat when cornering so is a handling mod...

Take a look here: HowStuffWorks "How do stabilizer bars work?" (http://auto.howstuffworks.com/question432.htm)

Do they improve anything??

YES! YES! YES! Especially on a mini with standard suspension. The difference is night and day. You will notice completely flat neutral handling through the corners. A great mod and I highly recommend it. Especially the rear roll bar! In the states this is one of the first mods people do. Over here it seems to be seldom done.

Buy them!

Sorted....thankyou for the replies guys...Iv got the deal of the century on them, but i will keep quiet till they are actually in my possession, i dont want to tempt fate!!
everyone seems to rave about them so cant wait to get them on...puttin eibach springs on at same time, cant wait!!

for a good reason the americans dont have corners on country roads :rolleyes:, they use them on flat autox layouts to provoke lift off over steer for tight corners, the minis anti roll bars esp in the case of the cooper S are already too stiff, i have my car properly set up on coilovers and it handles flat as a pancake with no nasty span of the anti roll bars, they really are a blunt instrument for people who do not understand what a car should handle like

soooooooo.what are you saying? they are rubbish??

yes, they are a hammer blow when what you need is precision fine tuning which only coilovers will allow, but that costs money but at the end of the day i would rather spend properly than waste a little ;)

I don't think that is the full story.

The mini has been engineered to understeer by BMW as a 'safe' setup.Fitting a stiffer anti roll bar, particularly an adjustable, on the back will allow this to be dialled out. The use of adjustable roll bars is very common in motorsport for setting handling characteristics for various tracks.

In the states this is seen as the first recommended mod - and not everyone there does autocross.

It probably isn't as effective on the track as coilovers but it is a lot cheaper and that might explain why it doesn't get so much support on here. It is also easy to reverse out if you want to sell the car.

sledge hammer - nut

the front one is way way to stiff on the cooper S, why try fixing one bodge with another

There's a lot of misunderstanding of the purpose anti-roll bars serve. You should try driving your car with them disconnected, you'd be shocked.

It's a complicated situation involving the shifting mass across the axis of the car. Generally speaking:
Large front anti-roll bar = more understeer
Large rear anti-roll bar = more oversteer

Balanced front & rear anti-roll-bar's = balance between oversteer and understeer
Larger anti-roll bars = more balanced handling.

In more general terms, stiff anti-roll bars suit soft sprung cars eg Lotus Elan. Conversely soft anti-roll bars suit firm springs.

Much better information available on the web. here (http://en.wikipedia.org/wiki/Sway_bar) for example.

I heartily recommend ARB upgrades for anyone who wants to improve the tightness of the turning in their car. It's not for everyone, my car used to wallow like a hippo in a heatwave before I fitted them. Some people like that vagueness and safety of predictable oversteer.
