I'm running 7/8ths front 5/8ths rear Addco bars which I believe equates 22mm front 16 rear and I'm using 250lb springs front and the nisom srpings rear which I think are 110lb?? The 250lb spring is as stiff as I want to go on treaded race tires,

Dave, I suspect that with the diff now open the car was likely over rotating and once it started lack of rear grip at some level would have to effect the cars ability to squat to a small or moderate degree. We know that a fully locked rear end requires a different set-up generally the car biased toward understeer on turn in. So not to belabor the point but if you've set the car up to perform with a LSD that performs like 30% or 50% fully locked dif and you go to 0% I'd expect it to turn like a fork lift if the set-up is unchanged......throw in the lack of forward bite and using the throttle to settle the car mid corner likely is less effective. If you think of the throttle adjusting the ride height fore and aft, the inability raise the front (dial in slight understeer) as well as rear squat for forward bite it makes sense to me that the car feels wayward.......................naturally a race engineer may tell me I'm way off the mark.............but given your feedback I'm sticking to my theory.
