I've seen a few good pictures on here but I can't find them now. The welding shop teacher at my dads school is supposedly very good and he's willing to take a stab at it. Does anyone have pictures of the finished product? Thanks!

Perfect, Thanks!

Here's a different approach that I used. Note in the 2nd picture that the little support sleeves under the sway bar bracket are very important to keep the sheet metal from collapsing. I'm going to write this up on my track car blog in a future article but the pictures should be pretty self explanatory.

Veryy interesting. I haven't spoken to the guy directly but I'm pretty sure he only knows he'll be doing the edges. We'll see how motivated my dad can get him

It also fails to address the bushing barrel.

We just did the sides on mine, sounds like when you reinforce everything else the weak spot becomes the bushing barrel.

Interesting, I've always just done the sides on mine and have not had any problems. Guess it wouldn't hurt to band the barrel.

The Boxed control arms made by Dave Klymm at Fabcar were made from chrome-moly sheet, and MUCH larger in cross section than stock. They were also IMSA approved. And the were NOT heavy. Works of art.

I'll admit I have no experience with any failure modes in these arms. I was simply going with the 944Spec approval to box weld steel A arms (Ref para. 14.11). Certainly anyone with a mechanical design background will appreciate that boxing parallel to the weak axis is much better than boxing across the weak axis. Note that the existing A arms are still fully inspectable from the back side.

Totally forgot to update this. I finally got the things back a few weeks ago and I've been driving them since. This guy is really talented and he did a great job, but I don't think he'd be interested in doing this too many more times. I will ask him though. The pictures aren't that great I know and I couldn't get the damn bushings out after I put them in
