I have been using the EBC Yellow on our big Mercedes and they have made it a lot better but do like to glaze a bit when memsabh is in the car. I also used the red on a previous car. I am certain others (Mintex etc) are good as well but I can attest to the EBC being good. I use their direct online store.
I think they also produced some disc and caliper sets earlier this year which have had good reports. Not certain if the Aero was included however.
