THE BIT THEY DIDN'T PUT ON THE BOX.
The hydraulic cylinder is not impressed by M badges.
Shared component cataloguing across the BMW Group means certain internal hydraulic components match identically across lines. The "M-Division" markup drives the M3 part to £110+, while the shared Mini/Standard BMW part number retails at £35–£45.
SO WHAT'S THE CATCH?
Transmission and engine variant may change fitment.
“The interesting bit isn't the badge. It's what happens when you search for the part behind it.”

Look for complete part numbers and revisions, make sure you're comparing the same quantity, and check the exact model/application. That's especially important with electrical, braking, steering, battery and other safety-related components.
