Dynamic Friction 830-80083L Disc Brake Rotor - Rear Left

Overview

The Dynamic Friction 830-80083L is a rear left disc brake rotor built for Mazda applications that call for a 302 mm rear disc. It features a slotted and drilled surface, directional brake face, and a rust-resistant coating for consistent service in demanding braking conditions.

Compatible With Mazda CX-30, Mazda CX-5, and Mazda MX-30 EV rear left applications, this rotor is a fitment-specific replacement for vehicles using the listed bolt pattern and dimensions. The 830-80083L part number is useful when matching the correct rotor for the rear axle on these Mazda platforms.

Key Features

• Slotted and drilled rotor surface for improved pad contact and heat management.
• Directional brake surface engineered for the specified rotation pattern.
• Rust-resistant coating helps protect exposed surfaces from corrosion.
• Geospec Silver Grey hat finish for a clean, finished appearance.
• 302 mm outside diameter with 5-lug, 114.3 mm bolt circle fitment.

Detailed Description

Dynamic Friction 830-80083L is a disc brake rotor designed around the dimensions and fitment requirements of select Mazda rear left brake applications. The rotor uses a slotted X drilled surface and a directional braking face to support stable friction behavior under repeated stops, while the plain disc finish and coated hat help balance function and appearance. For buyers searching for a Mazda CX-5 rear left brake rotor, Mazda CX-30 rear left rotor, or Mazda MX-30 EV rear left brake rotor, this part number provides a direct reference for the correct application.

The 830-80083L rotor measures 302 mm in outside diameter, with a 68 mm center hole diameter, 39.8 mm height, and 5-bolt construction. It is a practical replacement choice when the original rotor is worn, scored, or affected by corrosion. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation caused by rotor wear or uneven friction surfaces.
• Reduced braking consistency from heat buildup during repeated stops.
• Corrosion on the rotor hat or exposed braking surfaces.
• Scoring, grooves, or surface damage on the existing rotor.
• Fitment issues when replacing the rear left rotor on the listed Mazda models.

Installation Notes

Verify rotor diameter, bolt circle, center hole diameter, and rear left position before installation. Confirm the vehicle uses a 302 mm rear disc and the listed Mazda fitment before ordering. Match the directional surface orientation to the vehicle’s rotation pattern during installation.

Quality Assurance

Dynamic Friction supplies this rotor with a rust-resistant coating and Geospec Silver Grey hat finish for added surface protection and a clean installed appearance. The 830-80083L is engineered to meet the dimensional and fitment requirements listed for the application.
