Aftermarket adjustable control arms on the rear (just upper would do the trick) will allow you to bring everything back into alignment, and should eliminate the problem. Think about it this way -- you needed camber casters to correct the front end because the arms are now at different angles than designed because of the drop. You dropped the rear end to, right? So you need to alter the length of the upper (or lower) arms to make the rear sit closer to the same angle it would stock. It's a little more complicated than that because of the driveshaft. Basically you need the pinion shaft (where the driveshaft connects to the rear axle) parallel or just a little "nose down" from the transmission. Changing the control arm lengths will get you there. You can buy all four adjustable or just upper or lower, either will do what you need. I over simplified this a bit, but this will get you in the ball park and will work. Trying to figure all the angles is a lot of work and can be confusing -- this "rule of thumb" approach is easier and as I said -- it will work fine for a street car. A road racer would need to be a bit more exact.
