Tubular UCAs

I worked with Bill on designing the newer style "V" shaped tubular upper control arms. These new style "V" shaped ones are now the only ones available because the older ones were designed to be used with factory 15" wheels...When you mount a 17" wheel to the older style "U" shaped control arm, at full lock, the 17" wheel would interfere with the control arm. I took note of this and talked with Bill over the phone a few times, and I gave him a few measurements on how they should bend, he applied it, and everything worked fine...So that's why there was the birth of a new control arm. :)

Now that's the info I was looking for! I knew that RMS came out with a new design, hadn't heard they weren't making the old ones at all anymore though. Last time I looked at the website the pictures still showed the old set.

I bought a set of Hotchkis arms for that exact reason, bought a set of 17's for my challenger and found that they hit the uca's at full lock. I already wanted to take the CAP arms off my challenger though, so it was a good excuse. And the Hotchkis arms have relocated suspension points for the e bodies, so I went with them. The a-body version doesn't, so the RMS arms would be a good choice too.

And raleigh, the double adjustables use rod ends, so there are no bushings. May get a little harsh on a street ride.
