I received a set of Project Mu brake pads for christmas... fronts and rears. My question is, in one of the sets (don't remember if it's front or rear, i'm at work right now so can't look), there is only a metal clip on one of the pads... but in the other set all 4 pads have the metal clips on them... is this right or should they all have the clips?

 

anyone??? I PMed andy@performance a week ago (since performance nissan is where we got the brakes) and he hasn't responded yet...
