Basically if there isn't some type of "relieve" for the springs to allow it to turn, it will twist on itself and "pop" back out making a noise.

There are a few fix for something like this, but the most common fix is having a type of roller bearing either on the springs or the spring cap.

Just another thing to check, what coilovers is it?

100% this. If it happens when turning the wheel, it's from the spring not rotating freely on the strut body.
