I'm already slightly down a degree or so............so I either go down more or up 1 hole as has been suggested.
The consequence of breaking parallel , at least from going DOWN some is already noted. The result of going UP is not.

I'll try to keep this short.
You lowered your car and it doesn't wheelstand as much. When the center of gravity is lower in relation to the rear axle the car will not transfer weight as easily.
Did you lower the front at the same time?
I expect the solution can be found in the front suspension. How much travel? How much stored energy? What is your front spring rate?

I'm assuming your car is still a stick. Have you made any clutch changes? How hard does it hit the tires on the starting line? Do the tires slip or dead hook? Does the rear suspension squat, or lift?

Raising or lowering the center of rotation (ladder bar eye) primarily affects the reaction of force applied to the rear tires.
Lengthening the center of rotation affects the point of lift in relation to the longitudinal center of gravity, not an option for your ladder bars.
