PowerStop EBR630EVC Disc Brake Rotor - Front

Power Stop Front Genuine Geomet High Carbon Coated Rotor Overview

The Power Stop - Front Genuine Geomet High Carbon Coated Rotor (Part Number EBR630EVC) is engineered for reliable braking performance on select BMW models. Designed with high carbon cast iron and a rust-resistant Geomet coating, this vented disc brake rotor offers durability and consistent stopping power for vehicles like the BMW 323Ci, 325i, and Z4.

• Constructed from high carbon cast iron for enhanced heat dissipation
• Vented rotor design to reduce brake fade during extended use
• Geomet rust-resistant coating to protect against corrosion
• Nominal thickness of 0.87 inches (22.00 mm) with discard thickness at 0.80 inches (20.40 mm)
• Overall height of 2.00 inches (51.50 mm) and outside diameter of 11.80 inches (300.00 mm)
• Mounting bolt hole circle diameter of 4.70 inches (120.00 mm) with 5 lug holes

Detailed Product Description

This Power Stop rotor is specifically designed for front axle use on compatible BMW vehicles including the 323Ci, 323i, 325Ci, 325i, 325xi, 328Ci, 328i, Z3, and Z4 models. The high carbon cast iron material improves thermal conductivity and reduces the risk of warping under heavy braking conditions. The vented rotor design allows air to flow between the rotor surfaces, helping to maintain optimal operating temperatures and reduce brake fade. The Geomet coating provides a protective layer that resists rust and corrosion, extending the rotor's service life and maintaining consistent braking performance.

Power Stop - Front Genuine Geomet High Carbon Coated Rotor Product Line

The Power Stop - Front Genuine Geomet High Carbon Coated Rotor line focuses on delivering rotors with enhanced durability and corrosion resistance. This product line utilizes a high carbon cast iron base material combined with a Geomet coating, which is a zinc-based rust inhibitor that offers superior protection compared to standard painted rotors. These rotors are designed to meet or exceed OEM specifications, providing a reliable replacement option for BMW front disc brake systems.

Common Applications and Issues Addressed

• Replacement for worn or warped front rotors on BMW 3 Series and Z models
• Reduces brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust buildup that can lead to uneven pad wear
• Improves heat dissipation to minimize brake fade during aggressive driving
• Restores braking performance after rotor damage or excessive wear

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.80 inches) before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque lug nuts to manufacturer specifications for proper fitment
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Follow vehicle-specific service manual for brake system maintenance procedures

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet strict quality standards, ensuring consistent performance and durability. The high carbon cast iron construction combined with the Geomet coating provides long-lasting corrosion resistance. While specific warranty details for part number EBR630EVC should be confirmed with the supplier, Power Stop typically offers limited warranties covering defects in materials and workmanship.
