Should I build them

I thought about this project at one time and was considering a universal a-arm mount such as Afco they have many different types of upper a-arms and are much cheaper than the tubular stock replacements, and there are many different upper ball joint choices.

I have built a lot of circle track cars. We spent a ton of time researching front end geometry. Majority of them were built on Camaro subframes, however we did several Mopars. They are very difficult to adjust when in a stock location. The rules never stated that we could not move the upper a-arm mounting points. We tried with the stock mounts, but had poor choices in final suspension geometry when in bump. :thebirdm:
Afco makes a mount that welds in place. We had a hard time matching the tubular control arms up for the geometry we were looking for, so we ended up making our own. Not difficult to do, but you have to do your homework.:read2:

I dont think most street driven cars would easily benifit from it, but some might be able to.
We designed this kit as a replacement for the rusty one. As I said, I might consider in the future moving the mounting points a bit. A 1/4" difference makes amazing differences in roll and moment centers. Not sure how much difference it will make on typical street driven cruisers, but if someone is doing any performance/competition stuff, well the possibilities are endless.:-D
