I went back out there tonight with my car again after making a couple adjustments to get rid of the loose rear end and pulled some consistent lap times even with bad luck and motor trouble.
I loosened the diff a little bit as well as adjusted the droop to 7mm in front and that made the trick. The rear droop stays at 6mm. The car is now hugging the corners much better and doesn't take off on the rear end. Thanks guys!!
