We also removed the front control arms to have them freshened up with SuperPro USA bushings.
The front suspension bushings are all rubber and definitely needed to be replaced after 30 years.
We turned to our friends at Lucky 7 Racing in City of Industry, California to vapor blast and install the SuperPro USA polyurethane bushings into our suspension. Lucky 7 is an amazing shop of RX-7 experts and enthusiasts, who know this platform inside and out. They service cars from around the country and have the expertise to help with anything from simple service, to full engine and project builds.
Lucky 7 did an amazing job at restoring the suspension arms to better than new condition. The vapor blasting makes the arms look better than they ever did off the showroom floor, and the SuperPro USA bushings will deliver excellent performance.
However, the front upper control arm bushings were a little perplexing. We initially installed them as per the directions, with the flange on the outer side (as pictured).
The OEM front upper control arm bushing has the big, thick flange on the outer side of the upper control arm, and the inner part of the bushing is noticeably thinner.

I dig that clamp designed into the sway bar mount, very cool! Loving this build, almost a roller!
What is the overall goal for this car, Billy? You are putting so much money into it that you might never drive it to avoid scratches! Everything is top notch and I enjoy reading every installment.
The car is being built to be driven and to share the rotary platform to a new group of people and to demonstrate that with proper engineering, they can be reliable and extremely high performers. The car will be tracked and taken to many events. This is not going to be a show car or garage queen.
It is done as a well balanced reliable car and this and what we did to our STI are examples of what it takes to do it right.
Amazing job on the bushing work who did that for you
