I've been having trouble with my brakes vibrating when I'm stoping for a while now. I've replaced the rotors and the pads and there is still vibration. The car is lowered and has the bumpsteer kit and MAC C/C plates with poly bushing. My rotors were also replaced with slotted/drilled rotors. Has anyone else had this problem? Is it because of the suspension being so stiff or the slotted/drilled rotors or what? HELP!
