good pads for le ctsv are up there... i noticed a little shaking and, same as you, i wanted to get in front of it before it ruined the rotor. there are some cheap ass pads like $40bux that say they fit but i cant imagine how bad they are. oems are about $250, after market are about the same price and up.
but it seems after a nice heat cycle and try and make sure not to leave the pads resting on the rotor- hard brake and then stop and sit at light with foot on brake. they brake smooth again.
looking at ebc reds for them, seems they give up a little braking power but dust is wayyy less....the pads that are on this thing (guessing oem) absolutely cover the wheels with brake dust if i do a few hard stops
