How do i check if the spring ends have been incorrectly positioned?
Realistically I think you would need to take the strut out and tophat off to see where it is positioned. I didn't install my own springs so unfortunately I can't help much more than that.

The other possibility is that your top-hat bearing is starting to bind / fail. That can also cause clunking. There is usually no visual indication when this bearing goes, you just start to hear it.

The stock tophat bearings are fine for stock springs but you get some different forces going through them once you lower the car or increase camber which can cause binding and early failure. If this turns out to be your issue, the best non-OEM replacement right now is the Group-N, or if you want a bit more camber/caster then the Pedders mounts are the way to go.

Hope that helps you narrow it down.
