Interesting topic here, brings me to an age old issue I have always had with my car. Similar to Brian's car, it's a 5.50 SBC chassis car, 4 link strut deal with anti roll. Problem is when track conditions are good the car leaves straight with short wheelies of about 50 feet. But when traction starts to diminish, car drifts to the left while front tires are in the air. I've squared, I've added neg. preload to no avail. Maybe I need to add a little rear steer IDK.

I've seen other door cars do this also, what's your thoughts?
Negative preload is for high hp cars 1100 1200 hp up. Low hp like you have, rearend rotation controls chassis dynamics. I could fix it in a flash, although it would be a process of elimination, meaning it could be a few different things causing this phenomenon.
I suspect when the left side rear damper gets warm, it develops hysteresis (slack). Pull them both off. If they're gas emulsion, when you shove the shaft into the main body it'll come back out on it's own. If one does and the other doesn't it'll be obvious the problem (gas leaked out). If there not gas emulsion you can't do any kind of rudimentary test yourself like this besides cycling both listening for air in oil, but you could just switch the driver side damper to the other side. Try it like that, might be a easy fix.
