Some aftermarket lowering springs are designed to have "dead coils"; that is, parts of the spring that are completely collapsed when the vehicle weight is applied. And it can generate a noise.
Double-check to make sure nothing is loose (swaybar endlinks can be an issue), and you might want to...
The links above do omit Swift Spec-R springs, and they are worth a look.
They are very close in weight to OEM springs (most aftermarket springs are heavier than OEM coil springs) and like OEM springs, they have a linear spring rate (again, most aftermarket coil springs are progressive)...

Bear in mind, driven gingerly, I...
