The more important question that many people don't consider is brake bias. A car with good balanced front/rear brake force will feels like you slide forward instead of excessive nod during heavy braking.

Like some other suggestions, a safe bet is to get AMG kit designed for your car.

Otherwise, get a professional to fit something right sizs that don't overpower your rear brake. It is not always bigger the better. Else get a 4 piece set that change all 4 corners.
