Cheap Mercedes-Benz CLS Brake Discs

No, the W219 and W218 are completely different platforms, so brake discs from the first generation will not cross over to the second generation. The hub dimensions, disc diameters, and caliper mountings changed between generations. Always source discs matched to your specific generation and confirm the part number with the breaker against your registration.

Yes, engine size is one of the main factors that determines brake disc diameter and specification on the CLS, as larger, more powerful engines typically came with bigger brakes to match their performance. For example, a CLS 350 and a CLS 63 AMG within the same generation are very likely to have different disc sizes front and rear. Always tell the breaker your exact engine variant so they can match the correct disc to your car.

Trim level alone does not determine brake disc fitment on the CLS — what matters is the generation (W219 or W218) and the engine size. You may find cosmetic differences such as caliper colour on AMG models, but the structural fitment of the disc itself is driven by the powertrain, not the trim name. Confirm your engine variant with the breaker and they will identify the correct disc specification for your car.

The W218 received a facelift in 2014, and while brake disc specifications may well be the same across the facelift divide, mid-generation brake upgrades are possible and cannot be ruled out. You should not assume discs interchange across that 2014 boundary without checking. Confirm the exact part numbers with the breaker against both registrations to be sure.

No, front and rear brake discs are different parts with different diameters and thicknesses, so they are not interchangeable. On the CLS, front discs are generally larger than the rears due to the greater braking load on the front axle. When ordering from a breaker, always specify whether you need the front or rear discs for your axle.

The CLS W218 and the E-Class W212 do share underpinnings, and in some engine variants the brake disc specifications may overlap, but this is not guaranteed across all variants and is something you should not assume without verification. Disc diameter and caliper fitment can differ depending on the specific engine and equipment fitted to each individual car. Check the part numbers with the breaker against both registrations before purchasing.
