Hmmmm….interesting.
I always thought M Sport discs were 340mm regardless of engine size, unless you spec’d the M Performance brakes and then these came with 370mm discs.

I’m gonna physically check today to see what size discs I have.

I’ve sold hundreds of sets of these calipers. My info is 100% correct.

If your car is a 35d and has factory fitted blue M Sport brakes, it will have 370mm front and 345mm rear.

The M Performance calipers you mention are 370 units, but were only available as a dealer fit accessory (not factory fitted) and came in either Red, Orange or Phoenix Yellow.

Quick update: After weeks of researching the best prices of 370mm front discs, I stumbled across a private seller on eBay with a pair of reasonably priced Brembo grooved/dimpled 370mm discs.
Suspect they are the same as the OEM M Performance discs as they look identical.

As for pads, I can’t seem to find the Ate ceramic pads for the fronts, just the originals.
BMW genuines are £130, as are the Brembo Xtra’s.

Any recommendations for daily/fast road use to suit the Brembo grooved/dimpled discs?

ATE Ceramic pads: https://www.autodoc.co.uk/ate/13580115

IIRC the 340mm and 370mm calipers share the same pads

If not those then the Brembo HP2000s seem to get good reviews

I've stuck with OEM BMW and TBH they've been superb; great braking, quiet, not very dusty and have performed from some very hard/fast driving to dead stops with zero issues

OEM Jurid pads. They are quiet and bite very well from cold. Very dusty, but it comes off easily and doesn't attack the clear coat like a lot of aggressive fast road pads do.
