Description: Almost all street cars come from the manufacturer with an anti-roll bar as it is a common part of modern suspension systems. However they are designed to be overly soft for maximum comfort. An anti-roll bar does exactly what it says by reducing body roll in all situations. Every Dinan tuned anti-roll bar is built and tuned specifically for each BMW chassis. Lowering the amount of body roll keeps your BMW more level than stock (while still allowing just enough body roll) to improve mechanical grip. This improvement gives the driver a much more planted and confident feeling in every corner.

Front Anti-Roll Bar

Add a 25mm Lightweight Tubular Adjustable Front Anti-Roll Bar to reduce body roll, improve grip and stability while saving weight at the same time. This anti-roll bar is adjustable up to 45% to 93% stiffer than the stock bar*. This 3 hole bar can be mounted in 3 different positions with stock BMW end links.

• Less Body Roll
• More Mechanical Grip
• More Stable At Limit
• Large 25mm size*
• Stock bar is 23.6 mm on the M235i which means the new bar can be adjusted from 45% to 74% stiffer than the stock front sway bar.
• Stock bar is 22.5 mm on the 228i/320i/328i/428i which means the new bar can be adjusted from 61% to 93% stiffer than the stock front sway bar.
• Stock bar is 22.5 mm on the 335i/340i/435i which means the new bar can be adjusted from 54% to 84% stiffer than the stock front sway bar.
• 3 hole bar with 3 possible positions on the bar

So no go on a 340xi? if not any plans/timeline on 340xi sways?

Edit - if you click around on the webpage it does look like these work on the 340xi. And now I see that the 340 is mentioned in the bullet points. Can you confirm? If so, great news!

[rixride]

Are these worth any Dinan points?

[cncmastr]

Looks good, why do these take so long to install?

[RM7]

Hell yeah, I have to have these!

[Big Nodge]

As far as the install costs go, are there economies of scale in installing these at the same time as other suspension components like coilovers? Meaning if you plan to do both over time should you just install them at the same time to save on costs?

Any suspension upgrades I would reccommend doing at the same time to save on installation costs. You will benefit greatly in the labor front if you do.

In regards to the labor--- you can review the installation instructions at http://files.dinancars.com/webresour...551a70acde.pdf to determine if you think the labor hours can be skimmed shorter. Ultimately BMW book times are what they are and we need to fall in line with them. If you can get a shop to do it for less time more power to you.

Sways are worth a point.

First post updated. They do work with the 340i. Just forgot to list the application in the original post is all.

Thanks for the info.

in terms of controlling body roll, do you think the sway bars or stiffer springs/shocks have more of an effect?

From a perception standpoint to the driver the springs/shocks will do most of the work while sways will fine tune it and dial it down to 0 in most cases.

The fact of the matter is the stock springs are so soft any improvment there is a night and day improvement over stock in body roll and "floatiness".

do most people remove this if bringing in for service or do dealers not care in general?

Not even close IME, sways by far. The whole principle of sways is the cornering forces effectively increase the spring rate on the outside suspension, preventing the transfer of mass, but still giving you the compliance for traction in other situations (and with the inside tire). Taking a turn and having the car stay level is highly worth it IMO.

You can't "remove" sway-bars effectively, often times you have do things like drop the subframe, unbolt the shocks/struts to drop the suspension, etc. I had stiffer sways on my C5 SS and they were the best mod I'd done to date (considering engine and other stuff I did to other cars). With the sways, front strut bar, rear hidden receiver that also tied together the rear end, the thing was a handling monster (in a good way). My BMW is so far behind in terms of handling it's not funny, so I'm trying to bring it up and make it feel "passable" to me.

It's not like taking off an air intake or something to that extent, pretty significant labor is usually involved.

It's like any other mod, if the mod breaks something, it won't be covered. If something brakes independently from the mod, it has to be covered. Dinan says they stand behind their products.

Ordered mine F36 sways this afternoon With the ACS springs, Dinan re-flash of the active suspension I did and the sways, I'm considering it my "704 suspension".

I am not aware of anyone removing sways for service. Would be an expensive proposition to do so.

In general most dealers don't care as much about suspension mods as engine mods unless the car is so far slammed on the ground they can't get it on a lift.

Both front and rear require dropping the subframes to install, which takes quite a while... So if you upgrade sway bars, I HIGHLY recommend upgrading to Bimmerworld rear subframe bushings as well while you've got the rear subframe down. They are a great, relatively cheap upgrade - it's usually just the install time that scares people off.

Thanks for the tip, wasn't aware of those. Would probably add them if I go this route. Thanks! I'm still in break-in and learning the car so it's all in the planning stages currently. But I have noticed a bit of the disconnected feeling from the rear on quick transitions.

How about the underbelly brace in that thread? Worth it?

To be honest, I haven't noticed any benefit on the street from the F32 rear subframe tension strut...but I imagine it will serve some benefit, especially on track. I was back and forth on buying it, wondering if it was necessary with solid rear subframe bushings...but then I noticed that the new M3/4 cars have them (even with their solid mounted rear subframes), so I figured it must provide some benefit.

[Big Nodge]

Thanks. I don't track my car so some of this might be overkill, but I'm coming from an A4 with coilovers, sway bars, and a dts and my xDrive suspension feels very soft and floaty in comparison. Can't have that. But I'll probably put the tension strut on the back burner.

Scheduled to get my springs and sways installed on Wed.

[CZECHF30]

Guys please, what do you think are the best sway bars for F30 335i xDrive ? Dinan, HR, Eibach ?

[insanecoder]

Can these Dinan Sway Bars be installed DIY on a 340i?

On that note, any idea when springs and Shockware will be available for the 340i xDrive models?
