Purpose and compatibility

The presented brake disc is designed specifically for BMW F80 M3 and F82/F83 M4 models and is a component of the rear left brake system. Thanks to its factory geometry and precisely matched dimensions, the disc works with stock calipers and stability control systems, maintaining the original braking characteristics.

The vehicle placement specified as rear – left side minimizes the risk of errors when selecting parts and facilitates the planning of service work on the rear axle.

Construction of the 370x24 ventilated disc

The brake disc features a ventilated design, which improves heat dissipation from the working surface during intensive braking. The increased diameter and appropriate working thickness ensure a large friction surface, which translates into stable deceleration even during repetitive, heavy braking.

This solution is particularly beneficial in high-power cars such as the M3 and M4, where the brake system operates under increased thermal loads. Internal ventilation reduces the fading phenomenon while supporting even brake pad wear.

Benefits of using an original BMW disc

• Factory fitment – the disc is an OEM component, ensuring it maintains the correct geometry relative to the hub, caliper, and heat shields.
• Stable braking performance – the large diameter and ventilated construction promote consistent braking force across a wide temperature range.
• Compatibility with safety systems – proper operation with ABS, DSC, and other traction control systems, without the need for software modifications.
• Optimal characteristics for the rear axle – the properly selected thickness and weight of the disc support the braking balance between the front and rear axles.

Part condition and service application

The disc is in the category of used OEM components, which allows for economical brake system repair while maintaining the manufacturer's original specifications. This is a particularly attractive solution for comprehensive service work on sports cars, where the cost of new components is high.

Before installation, standard workshop verification, inspection of the working surface, and measurement of wear parameters in accordance with BMW service documentation are recommended. A correctly selected and installed rear left disc supports the uniform operation of the entire brake system, which is important for both safety and the durability of other components.
