Ive had EBC green stuff, red stuff and yellow stuff pads on all my mgrs, and they've been terrible, the bite from cold was poor and the bite when hot was poor, they didn't last on track, i tried mintex, the cold bite was ok but they were bad on track, i tried genuine rover pads, the cold bite was brilliant but they faded quickly, but you get all the shims and stuff which is nice, then i tried ferodo ds2500 they were the tits, but pricey, im currently using PBS pads with MTEC discs and the brakes are the best they have ever been, stay away from EBC pads and discs, they look nice but are poor compared to the competition.
also they dont list some of there pads for the rover cars so you have to search for other makes, for instance i wanted to try the red stuff pads for my zr 160, i had to search for honda ep3 for the rear pads and ek9 for the fronts, they are the same pads as the zr 160 but they dont list them for zr.
basically stay away from EBC, if you look at feedback on forums they will tell you the same thing.
before you change pads and discs, flush your brake fluid and change your lines for stainless, brake fluid should be changed every 2 years but no one ever does.
