Well I took my car to the shop this morning and turns out the front tires have minor cupping on the inner edges which was apparently the main source of noises & vibrations, when we initially took it for a test drive the tech thought it sounded like bad wheel bearings.. which is what everyone who rode in it thought.
But once it was on the rack they couldn't detect any bearing issues but noticed the front tire cupping and a warped driver side rotor which would explain the brake pedal pulsation especially under heavier braking (but it wasnt the source of my noise issue).
I took it to the shop that originally installed the tires and they did a free rotation.
The noise is much less noticeable now, it's still there but not as loud and I cant feel vibrations in the floorboard anymore.
The tire shop said the tires are very close to the tread wear limits and the person I spoke with recommended I go with Nitto brand tires next time?
The sad part is my current tires only have 7,500 miles on them.. I guess I wont be buying Falken brand anymore lol (At least not the ZE-512 model).
