get a panhard bar. it isn't just for cornering. the panhard bar helps to keep the rear aligned properly. since we don't have upper control arms, the torque arm and panhard bar take its place. your LCAs are trying to put the power to the ground and your torque arm is doing its job, but your LCAs are just fighting themselves because they don''t have any help from the top of the rear. you can get a panhard bar for like 80-100. its your best bet to solve your problem

From what I've read the more negative the pinion angle is, the more "bite" the car will have, up to the point of wheelhop. So setting it more positive should reduce the tendency to hop.
