Mine had a similar issue after the drop. If I let go of the wheel doing 80mph, the car will gradually merge to the right and will completely change lanes after five seconds. It's repeatable on various straight stretches, regardless of road condition or road crown.

Therefore, I have to drive with the wheel at -5° (counterclockwise) at all times.

This has strangely not affected tire wear. My front tires wear evenly on both sides, with the only deviance being a bias to negative camber, meaning the inner side-blocks are 1/32" lower than the outer tread blocks.

I've had it realigned twice, with no fix.
