This is driving me insane enough to sell the car. I'm so done with it.

Recently I modified my car.

Installed the SPC Adjustable Lower control arms, new Konig Hypergrams, brand new pilot sport 4s tires, and Tein Flex Z coilovers. Lowered it an inch.

Alignment was 0.05 toe out in the front each side, and 0.05 toe in in the front each side.

The day after I got my tires, one of them was punctured. It was running at about 15 psi (not completely flat at all) and I drove it 3 blocks to the nearest tire shop by my house to get it repaired.

A week or so later I noticed a humming sound. I feel like its coming from the front passenger side but it could be from the rear and my right ear is picking it up.

Its a hummmmmm hummm hummmmmmmmmmmm hummm, kinda whirring, high pitched sound that's barely audible but I can definitely hear it.


- It doesn't change with speed. It comes on at about 20kph and its consistent in frequency and volume

- It doesn't change with turning, or changing lanes

- Its hard to tell if it changes with road surface type, if it does its very subtle.

- I feel like it changes a bit when I go over a bump, but I'm not sure, its very quiet.

- Changing the tire pressure didn't help.

- It doesn't change when coasting, it doesn't change with acceleration, it doesn't change with braking either

- I feel like it gets quieter once I get over 100 KPH.


I've heard everything from its my alignment, or that the SPC bushings are harder and i'm hearing the rear diff.

Any thoughts?
