This seems surprising. While I don’t have a M340i, all BMWs I’ve had in the past have always had great brakes and I’d be suspicious if yours doesn’t. This does come with the complaint about brake dust, but unless you go ceramic won’t improve much with different pads though some might be a tad dustier than others.

Slotted rotors only help mitigate gas build up under constant heavy braking such as on a track, they won’t help with dust during regular driving.

What do the neighbors think when that guy starts up cold?!? :)

Enjoy always in good health!

Doors are kind of like cutting limbs off of trees. Whatever you think it weighs, double or triple it.
