July 13, 2011 - Naturally, the first thing I did after the cruise night was put the car up on jackstands.
I wanted to see if I could fit a rear sway bar. Then I decided to look for the point where the exhaust was touching the body. And while I was at it, I gave the whole car a good look-over.
Good thing, too. This is the passenger's side upper shock mount. This has to support the entire weight of that corner of the car, and it's been gradually twisting. It's possible that my springs were going into coil bind, but a telltale I'd put on one of the coils says no. However, I did have a set of 8" 225 lb springs on the car for a while, which would have had potential for coil bind. I suspect that's what happened here. Interestingly, the other side doesn't have any problem - and I welded along the top edge of that one, but not this one.
There is a design problem with my mount when I look at it. It doesn't have any reinforcement above the shock mounting point, which is right where it needs it the most. And that gave me my solution. I welded up the crack and added a brace that runs upwards from the shock bolt to another plate welded to the wheel well. I think it'll make all the difference. Naturally, I forgot to take a picture when I was done. I didn't do the driver's side today, I'll get it later.
It's inevitable that things like this will show up. This is a pretty heavily re-engineered car. That's why I like to poke around under the car once in a while to see how things are working.
While I had the shocks off to fix this, I changed the 300 lb springs for my 10" long 250s again. Yes, they've been on the car before. In fact, I think the current spring setup (375/250) is what I originally installed when I built it!
