Detailed Description

The Dynamic Friction 830-21054R rotor is built for rear right fitment on the Hyundai Ioniq 5, Hyundai Ioniq 6, and Kia EV6. Its 325 mm outside diameter, 12 mm nominal thickness, and 10 mm discard thickness align with the listed applications, while the 69 mm center hole diameter and 114.3 mm bolt circle support proper hub fitment. The slotted and drilled surface is paired with a directional brake face to promote even pad interaction under braking.

DFC Geoperformance Rotor - Drilled and Slotted is the product line used here, combining a performance-style surface pattern with corrosion protection on the hat area. This makes the 830-21054R a focused replacement choice for EV brake service where the original fitment calls for this rotor configuration. This part number is 830-21054R.

What It Is Used For

• Replacing a worn rear brake rotor on the listed EV applications
• Addressing rotor scoring, grooves, or uneven braking feel
• Restoring proper brake surface thickness within specification
• Supporting brake service when corrosion affects the rotor hat area
• Maintaining correct fitment for rear right brake replacement

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear right position before installation. Clean the hub mounting surface and inspect pads, caliper hardware, and wheel bearings during brake service. Confirm the directional orientation matches the vehicle side and rotor design before final assembly.
