sway bar
Is that the same as Progress Tech. ??? (these guys.... http://www.progressauto.com/ ) I can vouch for that bar, it's solid construction and works! You won't break that one.

If Eibach was smart they would have bought a bar from Proggesive Engr. 40 miles from them and offered to install on my HHR, as I will buy from Proggesive and throw the broken on Eibachs front door. Piss poor marketing as that was my background.

My 2 cents:
For the ones that think a bigger bar is not the way to go, I have to raise the B.S. flag.
First any quarter inch increase in the thickness of the bar, puts four times the amount of force on the bar in a turn.
I have a OTTP bar, one inch and a quarter[most other bars are one inch].
I have track time on this bar, and it plants the rear hard, and keeps it planted. Keeps inside wheel planted, and it does not lift, and does not make the front end push.
I have run this bar for about a year now, and it works. and will not break.
Want the ultimate in cornering, Pedders springs, and OTTP "Hardcore" bar, will do the trick. "Moon"

Honest and factual answers to "junk" sway bar issues on this sorry forum will get deleted.
Eibach has acknowledged their design error, where the stress is concentrated at the point where the rear mounting bolt hole "may" result in the bar breaking at that point, with documented failures. They are currently redesigning the bar, bit are estimating late July for the new design.
Meanwhile, Progressive and the "other company with the 1" copy" that makes a bar with the same lame design with low carbon steel (1020, which is NOT suitable for this application!) have seen numerous issues with permanent deformation due to poor materials not suited to the application!
Until the various companies update to better designs and materials, I can only recommend going with Powell RaceParts rear bars.

The Powell bar is the same bar that OTTP uses. Comes in either one inch or bigger, inch and a quarter. You want a Powell bar, contact OTTP[OverTheTopPerformance]. I'm using the Inch and a quarter bar, called the "Hardcore". It works for sure. "Moon"
