Lessons from Hallett #82

[Daniel Allford]

After Hallett I checked toe and camber, I was happy to see that I had gained a degree of camber up to -3 deg. but I didn’t like the ¾” of toe in. Closer inspection revealed where the camber and toe came from:

So I ground out the crack

And welded it up

I also discovered that both lower front shock mounts were broken

And the right rear upper shock mount bushing was gone, so I had no dampening.

Conclusions:
Don’t fly the car, air time is fun but it is bad for the suspension.
When the driver says the car feels funny, inspect it.
The 82 car should be quick at Eagles when it has all 4 shocks working and the front wheels are pointed forward

Active toe! Nice.

That is a omewhat common failure from my limited tracking og 4th gens. Someof the OEM beads look like the missed one of the two parts they were trying to attach. My old chassis had some of these parts welded.

Also check the diff (axle tube) where the PHB attaches.

Interesting break... I think I will inspect my car a little closer.

Also, check the front swaybar mount brackets. Mine are starting to show a crack and Blainefab sells some reinforced ones so it is another common problem.

I see tubular K members in the 4th gen's future.

Fourth gens win more because they car prep better than Mustangs. I least that's what we have been told. LOL

Would there be any value to building up the area as a preventative measure? (I know this guy who can weld pretty good.) And if the answer is yes, would that be legal?

My understanding is the rules don't say we can, so we can't. However, if I'm (hopefully) wrong, let us know. Car is headed back up to the shop for exhaust work by MY guy who can weld, and I'd like to have him beef this up too...
