When you lowered your car the stock pan hard rod pushed the rear axle to one side, to the left I think. If you look closely, I'll bet you can see that one wheel sticks out farther than the other, i.e. the axle is not centered. You can imagine for example if the axle is off center to the left, that the car would push to the right under load. As mentioned above installing an adjustable pan hard rod to pull the axle back to center would likely solve the problem.
