i believe he has a camaro judging from his previous posts, and you have a cts-v ?
not sure how the forums are laid out, i always figure it's about an f-body unless otherwise stated
from what little i know about wheel hop, i thought it was caused primarily by the tires and then the amount of suspension flex not keeping the wheels or rather the rear axle positioned. so you would be looking at the oem rubber bushings in the lca's, panhard bar, and torque arm.
I don't think the setting of the pinion angle has any affect on hop, what would have an affect is if that angle you set changes under load, and with an aftermarket torque arm it shouldn't.
but for setting the adjustable torque arm, you are setting that to have the ujoints at the front and rear of the drive shaft to be in phase.

1_FMF is correct, pinion angle has no effect on wheel hop/traction. It only affect u-joint angle which primarily causes driveline vibrations. However, if the only parts you have are what you mentioned I can tell you exactly whet the problem is and how to solve it. You need lower control arm relocation brackets. Right now your anti-squat is negative, and the reaction force of the suspension is actually unloading the tires. If you look at your car from the side, you will notice your control arms run at an upward angle to the rear end. They should be straight, or downhill at the rear. This is a common issue with lowered cars
