Cheap Mercedes-Benz G-Class Brake Discs

The G-Class has been built on the W460 (1979–1991) and W463 (1990–present) platforms, with the W463 receiving a major update in 2018 that introduced a heavily revised chassis and suspension — brake disc specs changed significantly at that point. A disc from a pre-2018 W463 is unlikely to fit a 2018-on W463 without confirmation, even though the body looks similar. Always confirm with the breaker against your exact registration before ordering.

Yes, engine output and weight distribution directly affect brake sizing on the G-Class, so the high-performance AMG variants such as the G63 typically carry larger brake discs than diesel models like the G350d or G400d. When asking a breaker for a quote, always give your engine designation and the AMG or non-AMG specification, not just the body style. This is one of the most important fitment factors on this model — do not assume any W463 disc is interchangeable across engine variants.

Yes, front and rear brake discs are different parts with different dimensions, and you must specify which axle you need — NS (nearside, left) and OS (offside, right) discs on the same axle are usually matched pairs but the axle itself absolutely matters. Tell the breaker clearly whether you need front or rear, and ideally quote your registration so they can verify the correct fitment. Never assume front and rear discs are interchangeable on this or any vehicle.

Trim level branding on the G-Class broadly reflects engine and powertrain differences rather than cosmetic packaging, so yes, the G350 (diesel) and G500 (petrol V8) are likely to have different brake disc specifications due to their different power outputs and weights. Unlike purely cosmetic trim differences where the same disc would fit, on the G-Class the model designation is a genuine guide to which brakes were fitted. Confirm the exact disc dimensions with the breaker against your registration to be certain.

The 2018 model year marked a fundamental chassis revision of the W463 G-Class, bringing a new front suspension setup and revised braking system, so 2018-on parts are unlikely to be a direct swap for a pre-2018 car. Your 2015 car sits in the pre-2018 generation and you should be sourcing discs from that era of W463 production. Ask the breaker to cross-reference your registration rather than relying on the shared W463 chassis code alone.

For brake discs specifically, the steering side of the vehicle does not typically affect the disc specification — what matters is the engine variant, axle (front or rear), and generation of the W463. A disc sourced from a European-spec car of the same engine and generation should dimensionally match a UK-spec car, but confirmation with the breaker against your registration is always recommended to rule out any regional or mid-production specification changes.
