Hi, I fitted the EBC discs & yellow stuff pads(kit) to mine back in 2018 & they were a definite improvement over what was in it, can't remember what pads/discs were fitted but they looked in good condition l just didn't think it stopped well. The EBC's had more bite & with less dust.
Pad material is rated with letters E F G H & they use one letter for cold performance & one for hot e.g EE would be the 'least' affective when the brakes are hot or cold where as HH pads would be the best in both conditions & you can get combinations of letters depending if you want good stopping with hot brakes & not quite as good when cold eg FH
I find pads are more readily marked in the motorcycle world. I've just fitted new Febi pads/discs to my daughters Kia & the pads weren't marked like the Mintex ones I fitted to my D2. Not sure if it helps but as long as the rest of the braking system is up to scratch most pads should do a pretty good job if they're E approved, all the best.
