I was wondering if anyone has felt a humming vibration at all speeds in the floorboard and foot pedal. I was thinking it might be the struts or strut mount. I'm lowered with ssc springs. Has anyone experienced this problem.

 

could it just be the feed back from drivin? my pedals and shifter vibrate a little, its nothing dramatic, but its just from feedback, either a rough road or stepping on it hard...
