Purpose and compatibility

The presented brake disc is designed for installation on the rear axle, with the versatility to be used on either the left or right side. This placement allows for consistent braking characteristics and proper interaction with the rear calipers in the W204 series C63 AMG model. The design meets the requirements of a high-performance braking system typical of the AMG version, which translates into stable braking force at higher speeds and during intensive use.

Technical and functional characteristics

The disc belongs to the Brake discs category, meaning it is a key component responsible for converting the vehicle's kinetic energy into heat through friction with the brake pads. The properly selected geometry of the disc's working surface allows for:

• maintaining a stable coefficient of friction across a wide range of operating temperatures,
• proper interaction with original AMG calipers,
• even wear of brake pads across the entire working surface,
• maintaining axial alignment and proper wheel guidance relative to the hub.

Thanks to its factory origin from a Mercedes vehicle, the disc maintains correct dimensional tolerances, which reduces the risk of vibrations, lateral runout, and uneven braking. This is particularly important in high-power cars, where the braking system operates under greater thermal and mechanical loads.

Condition, origin, and service application

The item is used, which allows for reduced braking system maintenance costs while maintaining the manufacturer's original specifications. This type of part can be an attractive solution in situations where it is necessary to replace a disc after a collision, mechanical damage, or excessive wear of the existing component, and the priority is to maintain compliance with the factory design of the AMG braking system.

Choosing an original, used brake disc is particularly beneficial for vehicles where maintaining the consistency of braking system components is essential – both in terms of performance parameters and compatibility with other rear axle elements.

Safety, selection, and cost optimization

To fully utilize the potential of the presented disc, it is recommended to install it in pairs on the axle and to check the condition of the brake pads, calipers, and brake lines. Proper selection of recycled parts allows for significant savings on service costs while maintaining an appropriate level of safety and driving comfort.
