Assuming the noise is coming from the front under your feet, check the Front Stabilizer Bar/Anti-sway Bar Mounting on the frame/chassis (which is under your feet) as well as the links from the bar ends to the suspension. I would see if you can change the noise by changing the Suspension Setting from Street to Sport to Track and see if the noise changes or stops. If you can change the noise by changing suspension settings, your noise is related to suspension oscillation/cycling when you hit those bumps in the road.
