I think the rear sport pads are the same as standard M pads.

They fit the M-Perf BBK just fine.

I've had the standard M pads on my M-Perf BBK and steel brake lines for almost 2 years and I run them in winter. I think they are fine and I think they have better initial bite, perhaps a bit better overall, but I also think that some of it is due to the steel brake lines and I also think maybe I should have stayed with the original pads. I swapped when I already had the steel lines.

I don't track that car but I do occasionally drive aggressively for long runs... 250-300 km highway going 200-240 km/hr or so which, of course, includes some hard braking and stops... and over time I noticed some vibration when braking medium to hard... and I think it may be due to the more aggressive M pad than what's supposed to be coupled with the brake kit and, therefore, some uneven wear and deposit on the rotors. It's not horrible but I do notice some vibration.

Occasional noise when cold but not bad at all. Lots of dust, just like the original pads.
