Don,
The replacement ones I got were lousy at first until they seated against the rotor. I've only replaced my rear ones. I got them from
NewSpeedmaster I'm not entirely satisfied with the performnace of the rear pad I installed (even after several 1000kms) and think they could be better. I can still lock up the rear wheel but it seems like I need more effort than before. I picked up these pads because I thought they would be a good compromise between the softer pads and ones that eat your rotors.
If you go with OEM, let us know if the feel is the same after they are broken in.
