Dynamic Friction 631-21057R Disc Brake Rotor - Front Right

Overview

The Dynamic Friction 631-21057R is a vented disc brake rotor with a slotted and drilled surface, built for vehicles that use a 5-lug, 114.3 mm bolt circle and a 350 mm outside diameter. It is a fitment-specific brake rotor for select Genesis G70 and Kia Stinger applications, with directional braking surface geometry for consistent contact.

Key Features

• Slotted and drilled rotor surface for improved pad bite and heat management.
• Vented rotor construction for better airflow through the disc.
• Directional brake surface for a defined rotation pattern.
• 5-bolt, 114.3 mm bolt circle fitment.
• Plain finish with a 350 mm outside diameter and 57 mm height.

Detailed Description

This Dynamic Friction brake rotor, part number 631-21057R, is engineered as a direct replacement-style disc rotor for select Genesis G70 and Kia Stinger front right applications. The slotted X drilled surface and vented design support stable braking performance under repeated stops, while the directional surface layout matches the intended rotation pattern. The 28 mm discard thickness and 30 mm nominal thickness provide the dimensional reference needed when comparing service wear and replacement requirements. For shoppers looking for a Genesis G70 front right brake rotor or a Kia Stinger front right brake rotor, 631-21057R offers the correct fitment profile for the listed vehicles.

What It Helps Solve

• Brake pulsation from a worn or out-of-spec rotor.
• Reduced braking consistency from heat buildup.
• Surface wear that affects pad contact and stopping feel.
• Rotor replacement needs on listed Genesis G70 and Kia Stinger applications.

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. This part is listed for front right placement only, so confirm the vehicle application and side before ordering. Inspect pads, caliper condition, and hub surfaces during service to ensure proper rotor seating and braking performance.

Quality Assurance

Dynamic Friction supplies brake components for service replacement applications, and this rotor is built to match the listed fitment and dimensional requirements. Part number 631-21057R should be matched to the vehicle application data before installation.
