In US F30 335/340 was coming with two different rotors sizes, same pad size, but 3 different materials:
1. Base (Grey calipers, 340mm rotor): Soft feel=Low dust=Garbage.
2. S2NHA code (M Sport-Blue Brembo calipers 370mm rotor): Lots of bite. Extremely aggressive=True BMW pad, on all EU models as base pad.
3. P337 M Performance (ANy color Brembo caliper, 370mm rotor): Soft bite, low dust. Garbage IMO.
Good thing S2NHA fits all Brembo calipers, base or Blue, regardless of rotor size.
Thanks for this. Although I have no complaints about the base brakes on mine. Better than most cars I’ve owned.
