Bumpsteer bracket (Page 4/6)
wftb JUL 23, 08:17 PM
I have had the car on a road course to see how the system works under extreme conditions and the results were very good. Nothing bent or worked itself loose, the car handled well so the next step is going to be a better upper arm mount. The stack of washers I have now did not cause any problems but I have a rough idea of a more permanent and adjustable solution.

It doesn't look like you get a lot of comments/feedback, but let me state that's pretty cool, and thanx for sharing your ideas and build.

Thanks for the reply. Very true that there no longer seems like there is much interest in this type of modification. Maybe the fiero has reached an age where people are more interested in restoration and preservation than mods. I am just happy that I can post my stuff on a site like Pennock's.

So if you wanted to improve on the RCC set-up, what would be on the list? I'm going to making some for myself. If there's any interest, I might make a few extra.

I am not that knowledgeable about suspension geometry to really answer. The RCC arms are really just stock arms made out of tubes, all the geometry is stock. The advantage is that they are lighter than stock and look better. The bumpsteer bracket works well with them, and I noticed an improvement when I bolted the tie rod directly to the frame. I wish I had thought of that when I first put it on the car, but I was basing my design on Yarmouth Fiero's. In hindsight, I think he has made a mistake. He does not come onto Pennocks anymore so I doubt if he has even seen what I have done with his idea.

I was meaning more along the lines of "the pinch bolt is too long and works loose" or "if the toe link attachment point on the fabbed bracket was moved closer in toward the spindle, there'd be more room for a 14" rim" or "this one's a little heavy" or "?"

Not to denigrate someone else's work but the original spindle bracket looks a little rough. I'll weigh the stock control arm just for the fun of it.

Thats because I made the spindle bracket, not RCC. I have never been one to grind off the rough edges, clean up rough welds and paint my work. I am lazy that way, always in a hurry. So my stuff always looks a little rough around the edges. What would I do to improve it? Probably paint it sometime.

When it comes to moving where the spindle bracket has the outer tie rod end I do not know if it could be moved inboard or not. I do have a bit of chassis design knowledge but it is all from Herb Adams book. So from researching the book I decided that the outer tie rod end had to be below the OEM tie rod end mount on a line joining to a line straight out from the ball joint ball centre.(the angle of the lower line that comes straight out from the ball joint was determined by the direction of the pinch bolt).So locating the rod end any where else may not put it properly lined up. Now a proper pinch bolt is hard to find. the OEM pinch bolt had a longer than normal unthreaded portion of the bolt. This was made like this so no threads(or very few) would be touching the groove in the ball joint stud. New ball joints usually come with a normal longer thread bolt. Makes for a sloppier ball joint stud and tightening it enough to get rid of the sloppieness usually bends the bolt.
As far as making the bracket look nicer, use of larger continuous pieces down the sides would help the looks and maybe lower the weight a bit. But the bracket as is- its not very heavy. I think it looks bigger in the pics than it is, it really is a fairly compact piece. I have not weighed it though.

My welding is decent but my grinding is even better!

I do work on cars that go to car shows so I tend to make it look pretty.
