Peter. Don' take it personally. I am speaking in generalities.

At the moment I have to do my Taurus SHO. It doesn't show at all from the outside but when you jack up the car you can't open the door.
Very similar to your situation.

I had a customers 72 Mustang convertible and it was the opposite. When you open the door the car would sag. The door would keep the car from springing.

I gave that one "out" rather then do it myself. It was a $10,000 repair.

I did a partial rocker on my Pantera. Right rear. About 20" of it.

I'm wondering if there is a left to right twisting on your car?

I have a roll bar in my car. It bolts to the bulkhead, the inner rockers and to the roof above the doors.

I can't say that it positively eliminated the twist but it certainly reduced it and strangely enough, the car feels more solid.

It may just be that I expect it to be stiffer? I don't know.

The floorpans are also lowered 2". If you look at what that does in cross section, you can see the increase in the depth of the "beam. It acts very much like the hollow section of the rockers, but in the opposite direction.

The only negative is that this probably will just cause stresses somewhere else? Then I will go to plan B, whatever that is. That's undetermined right now.
