I'm looking for the correct part number for the front brake pads of a 2016 435i xDrive Gran Coupe. Manufactured 03/2015. It has the M Sport aero kit but not the M Sport brakes. (rears are just basic floating calipers) Looking at RealOEM I think I need either 34106878878 or 34116878876 but these two parts look exactly the same and even cost exactly the same too. Are the front brake pads the same dimensions just with different compounds between non-Msport and Msport brake packages?
This at least lists the part numbers you mention - https://www.bimmerworld.com/About-Us/F30-M-Sport-Brakes/#335i Between that, & this, maybe you can eke out what you should have, or might want to try - https://www.turnermotorsport.com/t-brakes-F30-Brake-Differences Since ECS bought-out Turner, I'm not sure calling gets you anyone but an ECS sales rep sitting in front of their computer instead of anyone at Turner with their in-depth expertise & insight. A call to Bimmerworld possibly is a better bet.
So it looks like officially the part number I'm looking for is 34116878876, but it actually has the same caliper and rotor as the base models which specify 34106878878. My guess is that they're the same pad dimension spec with a slightly sportier compound. The reason I was asking it just because many aftermarket parts reference 34106878878 so I just wanted to see what options were available.
