Low Humming/ Whirring/ Droning Sound When Turning

Ever since installing my new wheels and front coils (even before I installed the rear coils), I've noticed a fairly loud and low humming (more so a very low frequency whirring/ droning) sound whenever making left or right turns. This was never the case with my stock suspension and wheels (it started the day I installed the front coils and wheels on the first test run). There is no play in the hub either.

At first I thought that the wheels may have been rubbing the coils as the fronts were pretty slammed, however I didnt find any signs of wear on either the wheel or the coils. I rose the coils up by about an inch and a bit anyways and now there is definitely enough clearance (as seen below). The fenders and outer tire also show no signs of rubbing.



I should mention that I am definitely due for an alignment though (needing to steer slightly to the left to stay straight), but I'm waiting for the coils to settle in first. Perhaps this could be causing the noise?

Currently on:

Fronts: 19x8.5 et 35 225/35/19 falken fk 452
Rears: 19x9.5 et 40 235/35/19 falken fk 452
Coils: ST V1
Everything has less than 100 KMs on them

I've also been reading around and have come to a mixed bag of reviews on the 452's road noise. Could the noise I'm hearing come from the tires?

Thanks!
