• Vented and slotted design enhances heat dissipation, reducing brake fade during aggressive driving or towing.
• Precision-machined rotors guarantee a perfect fit and smooth operation, minimizing vibrations and noise.
• Engineered to improve braking response and support increased stopping power compared to original equipment.
• Designed specifically for the BMW 328i xDrive (2009–2010), ensuring optimal fitment and performance.
• Manufactured with strict quality control standards to meet or exceed OE specifications.
• Suitable for daily driving, spirited driving, and light track use, providing a versatile upgrade for your vehicle’s braking system.

Construction & Design

The PowerStop SC4105 rotor kit features a robust cast iron construction that provides excellent thermal stability and resistance to cracking. The rotors are precision-machined to ensure a perfectly flat surface, which promotes even pad contact and consistent braking performance. The vented design allows for efficient heat dissipation, preventing overheating during extended braking or aggressive driving. The semi-coated surface treatment adds an extra layer of protection against rust and corrosion, extending the lifespan of the rotors and maintaining their appearance over time.

These rotors are engineered with a slotted pattern that helps remove brake dust, water, and debris from the pad surface, ensuring optimal contact and reducing brake fade. The combination of venting, slots, and coating makes these rotors a durable and high-performing upgrade suitable for various driving conditions.

Performance & Sound

With the PowerStop Rotor Kit, you’ll experience improved braking response and reduced stopping distances compared to stock rotors. The enhanced heat dissipation capabilities help maintain consistent performance during repeated or heavy braking. While this kit is primarily designed for improved safety and reliability, many users also notice a slight increase in brake pedal feel and a more confident braking sound, especially during aggressive stops. The slotted design can produce a mild, sporty brake noise that many enthusiasts find appealing, indicating effective pad and rotor interaction.

Installation & Fitment

The PowerStop SC4105 rotor kit is a direct bolt-on replacement for the factory rotors on the 2009–2010 BMW 328i xDrive. No cutting, drilling, or special tools are required for installation. The kit includes all necessary hardware and mounting components, making it a straightforward upgrade for experienced DIY enthusiasts or professional technicians. It is recommended to replace rotors in pairs to ensure balanced braking performance across all wheels. Proper bedding-in of new rotors and pads is advised to maximize performance and lifespan.
