I have some STs and they make a crazy annoying groan (low pitch) squeak. If I place my hand on the spring itself I can "feel" the noise/vibration which makes me think it's the springs.
I see how explained how the Swift springs' setup helps with noise. Wonder if my stock STs are binding to a degree as the rotate...

Nearly all coilover will have some spring binding as there is metal to metal contact. If you ever watch a coil spring compress, it actually winds up and when it decompresses it unwinds. If that rotating motion is somehow been limited(by upper and lower perches typically), you will get noise. Swift thrust sheets will help with that. Bearings will too, but at a much higher cost and require more maintenance.
