What does it mean when the inside rear tire lifts or it sounds like the car diffs out (maybe/probably at the same time)? I am running 2 lube on BMI front end and 4 in the rear tubes. If I recall correctly I have tried to go up and down one time on the lube but did not make a difference if I recall correctly.
This is caused by a couple of issues. For me when the car diffs-out it is usually because tire size is too big. I am assuming you are running the correct tires. I run 1/12 mod and run my tires at 1.55 front and 1.65 rear. 18 front springs with lube and associated black side springs. Don't be afraid to make the car softer.
