Second Hand BMW X7 Brake Discs

The BMW X7 (G07) launched in 2019 and received a facelift in 2022, and while the underlying platform carried over, brake disc specifications can vary across that facelift boundary depending on engine variant and any running-gear updates BMW made at the time. You should name both registration years clearly when asking a breaker, and ask them to cross-reference against your specific VIN or registration to confirm the disc diameter and hub fitment match before buying.

Not necessarily — the X7 was offered with a range of engines from the 3.0-litre six-cylinder petrols and diesels through to the 4.4-litre V8 M50i and the M60i, and larger, more powerful variants typically run bigger brake discs with a larger diameter to handle the extra weight and performance. Always tell the breaker your exact engine code or registration so they can match the correct disc size for your car, as fitting undersized discs from a smaller-engined donor car would be unsafe.

The xDrive30d (diesel six-cylinder) and xDrive40i (petrol six-cylinder) sit at different points in the X7's power and weight range, which can mean differences in brake disc diameter or specification even though both are six-cylinder all-wheel-drive models. Confirm the exact disc dimensions against your registration with the breaker rather than assuming they interchange on the basis of similar engine size alone.

Trim level alone — whether your X7 is a standard xDrive model, an M Sport, or the full M60i — does not change the brake disc fitment; what matters is the engine variant and generation, not the trim badge or interior specification. Be aware that M Sport and higher-spec models may have larger calipers or different pad specifications cosmetically, so mention your trim to the breaker so they can check the full corner assembly matches, but the disc itself is driven by engine and weight rather than trim name.

The 2022 facelift marks a meaningful change point for the G07 X7, and while the body structure was carried over, it is not certain that front brake discs cross freely from pre-facelift (2019–2021) cars to post-facelift (2022 onwards) cars given the potential for running-gear revisions at that point. Name both the donor and recipient year to your breaker and ask them to verify disc diameter, hub bore, and bolt pattern against both registrations before committing to the purchase.

Front and rear brake discs on the BMW X7 are different parts — the front discs are larger to handle the greater braking load, while the rears are smaller, so they are not interchangeable between axles. When asking a breaker, specify whether you need nearside or offside and front or rear, and confirm the disc diameter for your engine variant to make sure you get the correct part.
