Indiglo pedals...

I just bought some indiglo pedals (civic Type R automatic) and the gas pedal fits just fine over the original, but the brake pedal is smaller in length than the original...I still went ahead and installed them, but that brake pedal looks all half-ass. These are the kind that you install by bending these metal pieces behind the original...anyone tried these? Ohh ya, one more thing. It also makes a light buzzing noise that bugs the crap out of me! Should it be doing that?
