Looks good

One question, why didn't you put your agxs on with the knobs facing in. It makes adjustments SO much easier.

No need to remove tire or anything.

um, why would i have to remove the tire? lol... they face out so i can see what setting they are on, reach my arm in the rim and turn it. So i dont have to look like a goof under the car.

Looks pretty strait forward to install. That will be my next suspension upgrade

Ummmm.....

Is that installed correctly (meaning, with all the pieces it came with)? I hope that isn't the way it comes. There is no way for the bar to work properly bolted directly the the axle like that.

Really?? Don't all the bars bolt to the axle?? Sure the Addco & eibach connect to the bottom but does that really make that much difference??

I'm pretty sure its just the design of the bar

It doesn't really matter where it bolts (assuming that we all know it has to bolt somewhere near the end of the arm, but that an entirely different story), but it can't be a solid attachment like that. There needs to be something that will deflect under load, some sort of bushing, and the lower strut bushing doesn't cut it. A solid attachment like that will lead to premature weakening of the spring steel the bar is made of.

so now are you still trying to say it doesnt work, or that the steel may break? i know a couple people who have had them on for quite a while and have had no problems. They also have had the eibach set and went back to a progress and stock front because they liked it better.

Alright, ill pitch in what knowledge and experience I have with this bar, and a few others I have had.


I have had the rksport 22mm rear, along with the eibach rear/front. And now went back to the OEM 03+ front with poly bushings, and the progress 22 rear. It has been the most NEUTRAL setup from all of them that I have had. And also provided the LEAST amount of roll. The RK design had the most, and also hung extremely low, which doesn't help with how low my car sits. The bar does it's job while sitting in the car, and is shimmed away from the torsion beam, along with having poly bushings on the face of the beam, I dont see how it could stress it out, or weaken it. Only stiffen it and make it that much stronger? Correct me if im wrong.

Wow, I had no idea that the progress bar installed like that. A solid mounting is much more efficient than endlinks. Cool!!

Not that it will break, it will weaken. Take a bar like this (solid links) thats been in use for a year or so, and check its rate. I guarantee it will be weaker than a bar that has a bushing at the end instead of a solid attachment. It will work, but not to the same extent as a properly designed end link with a bushing of some sort.
