I have had a similar experence. I got sent disks for the wedge 200. I would send the disks back and get them to send you dimpled and grooved (not drilled because they make a rapid popping sound) it shouldn't cost anything (mine didn't)
I fitted drilled and grooved disks and the brakes went from ok to, hit your passangers face on the dashboard.
And you so get used to the sound they make.
