Had to remove the 10mm rear spacers yesterday, but now I hear a faint ticking noise in the cabin below the e-brake. Starts around 20 mph or so, very faint. Funny thing is it goes away when I pull up the e-brake a cm or two. When I release it, the ticking noise comes back. The noise sounds like it may be wheel related as it goes faster as the wheel go faster, as opposed to engine or drivetrain related. Any ideas? I don't think I did anything that would cause this. It's faint but it's driving me nuts.
