Brake pads Ferodo or OEM BMW

I run the Ferodo DS2500 which would probably meet your criteria. Fair warning though - they make noise, especially in the fixed Brembo calipers. You have to regrease them every few months.

Buy Ferodo DS2500 brake pads then buy rotors according to your budget, forget about drilled rotors if anything go with slotted and if within your budget get two piece rotors in order to save unsprung weight.

Genuine BMW pads and discs only. Driven 200k miles in my beamers. Even the e46 gets genuine BMW factory brakes. My 640i got new genuine discs and pads about a year or 2 ago. (£550 in parts, £80 labour).

Ferodo ds2500 is a great option. I’ve heard yellows are noisy/dusty. I’ve inhaled plumes of it first hand on the track.

Stock PP1 pads are Ferodo DS2500. Actually pretty good.

The pads on my 2019 Alltrack are wearing nicely as there is plenty of life left at 52,500 miles.

I can't say much towards your brakes since I have a G30. However, I was quoted $1850 for my front M Sport brakes. I ended up doing it myself for $900 in parts only. It's not very complicated.

Previous discs and pads were OEM and the new ones are Ferodo. As mentioned previously, the sound was there with the OEM parts as well.

I track the car and use the DS2500 pads with DOT 4 brake guild. Let me tell you this from personal experience, the stock pads fade real quick. After 2 sessions or so (15mins sessions), the brakes get real spongy.

Welcome - get used to it, unfortunately!
