Last night I installed a third chassis mounted Pro-Touring style rear sway bar on my car. The first one I never even finished with the install because it would not clear the lower control arms I had on the car at the time (the company graciously accepted the return). The second one required me to heavily modify the axle mounts to get it to clear my 9” housing and also took quite a bit of reconfiguring to get the end links to clear my tail pipes and lower control arms. I took it back off right away after testing showed it to be much too stiff for my application.
For over a year now I have been asking Ramey at UMI Performance to build a chassis mounted rear sway bar of the right size to work for how I use my car. They did just that and I finally ordered one of their ¾” solid rear sway bar kits for a G-Body and installed it last night. I’m not kidding when I say it took me less than hour start to finish for the install. The hardware UMI provided with the kit is top notch and everything fit just perfect on the first attempt. For example, the brackets used to attach the end links to the chassis, the other 2 bars used a single bolt to hold the brackets to the frame… the UMI kit uses not only 2 bolts but also a reinforcement plate behind the chassis to secure the bracket to the frame.
And the end links are short enough to allow the bar to sit at a decent angle even with the lowered stance my car sits at.
The bar clears the axle housing with zero issues and sits just about as perfect as it can.
Overall, I’m impressed with the build quality and more importantly the design that went into this product. I can’t wait to see how it performs on the street and on the track. My first autocross test n tune is April 9th. I’ll have my new UMI G-Body front chassis brace installed by then as well.
