i was told years ago to lower your lbs of air in the rear so
the tires could expand and that way you would get a wider patch of rubber on the ground so the tire would grip better.....

I think lowering PSI in the rear tires does make a difference, but it will depend on what profile tire you're running as well. My best ET was done with tons of weight in the trunk and with the tires nearly 10psi below what I run on the street.
