BMW M4 Brake Discs Replacement Parts

The BMW M4 has its own dedicated high-performance brake discs that are distinct from standard 4 Series units — the M4's significantly uprated brakes are matched to its power output and are not shared with non-M variants. All M4 variants across both generations were fitted with these larger, M-specific discs front and rear. You will need to source discs specifically listed for the M4, not generic 4 Series parts.

The F82 M4 ran from 2014 to 2020 as a single generation, so a 2015 and a 2020 car both sit within the same F82 body generation and the discs should broadly correspond. However, there were mid-generation brake specification changes on some F82 cars, so you should confirm the exact disc diameter and specification against your registration with the breaker before buying. Never assume fitment purely on generation alone.

The F82 and G82 are entirely separate generations — the F82 ran from 2014 to 2020 and the G82 launched in 2021 on a different platform — so their brake discs are not interchangeable. The G82 is larger and heavier, and its brake components were redesigned accordingly. Always quote your registration to the breaker and confirm you are getting discs listed specifically for your generation.

The Competition specification on both the F82 and G82 M4 brings power increases but the core brake disc dimensions are generally the same as the standard M4 within each generation. Trim level alone should not change which discs you need, though the breaker may flag differences in calipers or pad specifications between variants. Confirm against your registration with the breaker to be sure, but do not be put off sourcing from a standard M4 if the generation matches.

The F83 M4 Convertible shared its front subframe and running gear with the F82 coupe, so brake discs are generally interchangeable between the two body styles within the F82 generation. The heavier convertible body did not result in a different brake disc specification in most cases, but it is worth confirming with the breaker that the part is listed for both body styles before purchasing. When in doubt, quote your exact registration.

The xDrive M4, available on the G82 generation, shares the same brake disc sizes as the rear-wheel-drive G82 M4 in most configurations, since the brake sizing is driven primarily by the car's power and weight rather than driven axle count. However, because this is a relatively recent variant, you should confirm with the breaker that the discs they are quoting are listed against your specific xDrive registration rather than assuming a straight swap from a rear-wheel-drive G82.
