Well that's the end of it right there. There is nothing at all you can
do about that, and as I said in another post, increasing caster will
make that worse. Another influence is the width of the tires. The
wider they are, the more the car will react to the road. If you are
comparing this car to another one, it's pointless unless the cars are
identical.

That's not unusual.

But how do you know that it's "flat"? Crowned is one thing, but the
road surface is not necessarily level, and that's impossible to
determine visually.

You can't use a kit without elongating the holes. There might be ball
joints that will allow a camber/caster adjustment, though.

To be honest, I don't think there's anything wrong with the car. But
if on the exact same stretch of road, in the same lane, it sometimes
goes left, and sometimes right, that's something else entirely, but I
don't think that's the case after reading this post.
