Do you know if they are supposed to feel a little softer when pressed?
I picked up 530i also with the same M-Sport Red sport brakes but that brakes feels firm.
Interested in knowing who has the same Red brakes on 40i. Thank you

I think everyone's initial experience varies with BMW brakes and M Sport brakes. Mine had an initial softer bite when braking with more travel and pressure required than my previous F15, but overtime they feel more firm with reduce pedal travel after my first maintenance.
Depending on G30 model, there are 2 front M Sport ventilated brake disc sizes equipped: 530i/530i xDrive or 540i/540i xDrive/M550i and all models with 2NH share identical rear M Sport brakes.
530i / 530i xDrive:
Brembo 348 x 36 fixed caliper 2-part 4-piston with bonded brake pads for noise reduction
540i / 540i xDrive / M550i
Brembo 374 x 36 fixed caliper 2-part 4-piston with bonded brake pads for noise reduction
Rear 2NH M Sport brakes:
TRW 345 x 24 Grey cast iron, electric parking brake actuator, greased pad backing plate (Bonded brake pads are not used on the rear axle)
TLDR;
530i / 530i xDrive / 540i / 540i xDrive / M550i will have similar front Brembo fixed 4 piston Brembos and TRW rears as BMW X5s with towing/3rd row and 2NH M Sport brake option but smaller discs front and rear
530i / 530i xDrive with 2NH M Sport brake option will have equivalent front and rear discs to xDrive40i w/ 3rd row: 348x36 + 345x24, ventilated
540i / 540i xDrive with 2NH M Sport brake option will have equivalent front and rear discs to X5s with Towing package or 50i base: 374x36 + 345x24, lightweight ventilated
X5 xDrive40i with 2NH or X5 M50i will have the largest front and rear discs compared to G30s with 2NH.
