You are understanding correctly, although I have never seen even a stock car that doesn't have any pre-load. It is possible though. And a stock car isn't corner balanced, which is unnecessary unless you are tracking the car.

A correct corner balance is with you in the car or substituted weight, so it will be different for every car since we don't all weigh the same.

So if I get this correct, you'll want to corner balance the car so that while you're sitting in it you avoid undistributed pre-load on the sway bars.

(thinking that while you sit, you'll preload the bar on the driverside if you don't corner balance correctly)

Yes?

Everybody seems to make fronts. Are rears less important?

You need rear as well to eliminate pre-load.

.....I haven't found any to fit OE bar yet.

slightly off topic but is everyone still using the stock ARBs??? their doesnt seem to much out their for the z4m?? however the stock bars are quite thick compared to other vehicles....

seems some use the e46 bars BUT..... they arent quite a direct fit i here.. i did notice that KW have what i think would be a nice upgrade without being silly and risking ripping the mount points....

29mm front and 24mm rears....

I'm using a E46 M3 H&R front sway bar (30mm).

3-way adjustable, I have it set on medium stiffness right now. I'm leaving the rear sway bar stock. I like how the rear rotates.

TCK confirmed that the H&R bar is a direct replacement, and indeed it was.

I do need to reinforce my mounting points, anytime you go with a larger bar you will need to do so IMO.

I'll see if that helps the search.

H&R make front and rear now http://store.uucmotorwerks.com/z4-and-mz4-c386all.aspx
GControl is the only other choice I'm aware of

1mm is not worth the money.

Not to mention single adjustable.

Don't regret my purchase at all.

I see the 1mm size difference
I didn't notice the single vs 3 way adjustable difference in the two

Any word on the fit?
From what I can dig up, the issue is the way the OE presses over the bar stub.

http://m3.madrussian.net/diy/rear_ei...ay/diypop6.htm

There has to be tons of slop in the OE bar.
I hardly see much point in upgrading mount bushings with these things.

The Turner rear end links were a no go. I guess they're a press on type and our rear sway bars require a bolt on style.

I suspected they were a no go.
I think it's the OE that are press fit.
All others bolt the link in place.

I've pretty much decide to go with the Turner E46 M3 ARBs with adjustable end links.

I may have mixed up which attaches which way. Everything is still at the shop cause it's too low to get in my garage now. I just hope Turner will cut me a couple days slack on their 30 day return policy since they told me they'd work.

Edit: ...and Turner was totally cool about the return.

Do you know for a fact that the e46 bar fits? I hadn't really intended to upgrade sway bars at this point so I'm kinda bummed since now I can't really properly corner balance but I think I'm done with this project for now. Other priorities have come up.

You only need one adjustable per side.
