Technical specifications and intended use

The rear brake disc set has been designed for the rear axle of BMW vehicles, with dedicated placement for the right and left sides. The use of a ventilated design combined with perforation promotes even heat distribution across the working surface, which reduces the risk of overheating and loss of braking efficiency. The 345 mm working diameter and 24 mm thickness allow for compatibility with properly selected brake calipers and pads, creating a cohesive system with predictable behavior. The perforations on the working surface support the discharge of gases and debris generated during brake pad operation, which improves contact between the lining and the disc. As a result, the braking system maintains stable parameters even during repetitive, harder braking, which is important both in highway driving and in urban conditions.

Benefits of using ventilated and perforated discs

The use of ventilated and perforated discs on the rear axle of a BMW translates into a number of practical operational benefits:

• more even heat dissipation from the disc working surface,
• reduction of fading during repetitive braking,
• consistent cooperation with the electronic stability control and safety systems,
• better discharge of dust and gases from the contact surface between the pad and the disc. Thanks to these features, rear ventilated and perforated discs are a reasonable choice for drivers who expect predictable vehicle behavior during braking, without the need for typical racing solutions.

Condition, origin, and BMW fitment

The offered set comes from the Suspension replacement kits category, which facilitates selection during service work involving the rear axle of the vehicle. The items are in used condition, which allows for an economical approach to repair while maintaining proper fitment for a specific BMW model. The placement on the vehicle covers the rear axle and both sides, making the set suitable for simultaneous replacement of both discs, which is recommended for the sake of even braking system operation. It is always worth verifying the selection of discs for a specific vehicle version against the OEM part number and interchangeable numbers in the technical specification. This helps avoid installation problems and ensures compliance with the manufacturer's factory standards.

Practical installation and operational tips

When replacing rear brake discs in a BMW, it is recommended to:

• install discs in pairs on both sides of the axle,
• check the condition of brake pads and lines,
• inspect the hub surface and clean it before installation,
• properly tighten the mounting elements according to the vehicle manufacturer's recommendations. Such an approach promotes even system operation, minimizes the risk of disc runout, and ensures stable performance of brake assist systems. Comprehensive rear axle service in a single maintenance step reduces vehicle downtime and makes planning future inspections easier. If you are planning a comprehensive repair or upgrade of the suspension and chassis area in your BMW and need other elements from the same group, such as control arms, links, or bushings, check the available parts in the BMW suspension replacement kits category.

Technical support and additional information

When selecting used parts for a BMW, including brake and suspension components, it is worth using reliable sources of knowledge. If you want to refresh the look of your car and better match wheels to the vehicle's technical parameters, an article discussing the selection of used alloy wheels, ET offsets, and bolt patterns may be helpful – you can find it here: Do scratched rims ruin the look of your car?
