I am thinking about changing my stock plain black brake and gas pedals on my automatic xB. I was wondering what options there are out there for doing this. Does the whole pedal get replaced......and if so how hard is it to do this? Or is it just a cover that fits on-top of the current pedals? Seeing that these two little things are what makes me go and stop.....I want something that is safe and not make me get into an accident.
