Dynamic Friction 9504-31090 DFC GEOMET Coated Plain Brake Rotor Kit

Each rotor is precision-manufactured using premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability, and is finished with a genuine GEOMET® corrosion-protection coating applied to the entire part — including the hat — for a distinctive silver-gray finish that fights rust far better than conventional paint or zinc coatings.

Key Features:

• GEOMET® coating processed dry and shipped dry — ready to install with no additional preparation required
• 100% precision mill-balanced for smooth, vibration-free stopping at any speed
• Fine-turned to a maximum of 1.6 RMS surface finish for improved initial rotor and pad break-in
• Non-directional braking surface promotes faster, more even brake pad bed-in and quieter stops
• OE vane configuration ensures proper and maximum heat dissipation
• Disc Thickness Variation (DTV): .010mm maximum; Lateral Runout: .050mm maximum
• Each rotor passes a 100% electronic inspection station verifying all critical OE specification attributes
• Outside diameter: 324mm (12.76 in); Nominal thickness: 21.8mm; Discard thickness: 20.4mm
• 5-bolt pattern; Center bore: 75mm

The GEOMET® finish is safely swept away by the brake pad friction material during normal break-in with no harmful effects, making installation straightforward and efficient. Backed by Dynamic Friction Company's manufacturer warranty, the 9504-31090 kit delivers confident, consistent pedal feel and reliable braking performance as a direct replacement for worn OE rotors.
