Purpose and fitment for BMW 330i E90 / E91 / E92

The set has been prepared for the rear axle of the BMW 3 Series in the 330i version, covering installation on both the right and left sides. The working diameter and thickness of the discs are adapted to the factory configuration of the brake system in these models, which facilitates installation and ensures proper cooperation with calipers and brake pads. By maintaining the original geometry of the friction surface, the brake system maintains the correct braking force characteristics and stability during intensive use.

Technical characteristics of the rear brake disc set

The rear brake disc set with dimensions 336x22 has been designed to work in the standard hydraulic system of the BMW 330i, taking into account the loads typical for a driven axle. The design of the discs allows for uniform heat dissipation from the friction surface, which reduces the risk of overheating and vibration during braking. The use of an appropriate working profile promotes stable contact with the brake pad, which translates into a predictable brake pedal response and consistent braking performance.

Benefits of using pre-owned brake discs

Choosing a used set of rear brake discs for the BMW 330i E90/E91/E92 allows you to reduce service costs while maintaining proper fitment to the hub, caliper, and pads. This solution is particularly beneficial for comprehensive maintenance of older vehicles, where both the economic aspect and compliance with factory specifications are important. Maintaining the proper condition of the discs on the rear axle has a direct impact on vehicle stability during braking, especially at higher speeds and in emergency situations.

Installation zone: rear, right and left side

The set includes components intended for installation on the rear axle, on both sides of the vehicle. This solution allows for the simultaneous replacement of discs on the right and left sides, which is recommended from the point of view of uniform brake system operation. Maintaining symmetry of wear and friction parameters on both sides of the axle affects the stability of the vehicle's path during braking and reduces the risk of the vehicle pulling to one side.

Support for selecting used brake system components

If you want to take a conscious approach to purchasing used brake components and verify what to look for when assessing the condition of discs, calipers, or ABS components, it is worth using practical tips. You can find a detailed checklist in the article: Second-hand brake system – how to safely choose discs, calipers, and ABS?, which will help you assess whether a given component meets safety requirements.
