You would have to constantly relayer the oem discs with the sport pad material to keep disc wear and squeal to a minimum, but this is impossible on normal driving, thus my decision to swap them back to the standard pads, then swap to the performance pads for track days and my long road trips.

As to the different discs that are meant to be fitted with the sport pads, I have no idea whether they are a more resilient compound, although realoem does state that the standard discs are not to be fitted with performance parts.

There are no magic pads that will do everything without any downsides. Lots of people have 2 sets.
This is great info. Thanks.
