BMW 7 Series Brake Discs Replacement Parts

The E38 (1994–2001) and E65 (2002–2008) are completely different generations with different subframes, hub carriers, and brake specifications, so the discs are not interchangeable. Engine size also plays a role within each generation, as larger-engined variants such as the 740i and 750i typically ran bigger disc diameters than the six-cylinder models. Always quote your exact registration and engine code to the breaker so they can pull the correct fitment.

The E65 7 Series received a facelift in 2005, and while the basic platform carried over, there were running changes across the production run that can affect brake specifications — particularly on performance and larger-engined variants. Whether discs cross the facelift boundary cleanly is something you should confirm with the breaker against your exact registration rather than assume.

Not necessarily — larger, more powerful engines like the 750i often require bigger brake assemblies to manage the additional weight and performance, so disc diameter and thickness can differ from a 730d in the same generation. Always tell the breaker both the engine size and your registration so they can match the correct specification.

Standard trim designations on the 7 Series — such as SE, Sport, or M Sport — do not in themselves change the brake disc specification, which is driven primarily by generation and engine size rather than interior or cosmetic package. However, if your car has an M Sport or individual specification with larger aftermarket-style brakes fitted, the disc size may differ from a standard car, so it is worth mentioning this to the breaker when you enquire.

The G11 is the standard-wheelbase 7 Series (2015 onwards) and the G12 is the long-wheelbase version of the same generation, and they share the same front and rear brake specifications across equivalent engine variants. Confirm the exact engine code and any M Sport package with the breaker, as there are reports of mid-generation brake upgrades on this platform that may affect compatibility.

Front and rear brake discs on the BMW 7 Series are different sizes and are not interchangeable — the front discs are generally larger to handle the greater braking load. When contacting a breaker, specify clearly whether you need nearside or offside as well as front or rear, and provide your registration so they can confirm the exact dimensions for your variant.
