Detailed Product Description

This DFC Geoperformance Rotor - Drilled and Slotted is crafted to meet the demands of daily driving and moderate performance conditions. The vented design improves airflow to reduce heat buildup, while the drilled and slotted surface helps evacuate gases, dust, and water for improved brake pad contact and reduced brake fade. The rotor’s nominal thickness of 28 mm ensures durability, with a discard thickness of 26 mm indicating when replacement is necessary. The Geospec silver grey hat finish provides corrosion resistance, extending rotor life in various weather conditions.

The directional surface pattern is engineered to optimize braking efficiency and maintain consistent pedal feel. With a 5-bolt hole configuration and a 114.3 mm bolt circle diameter, this rotor is compatible with specific Lexus and Toyota models, including the Highlander, RX330, RX350, and RX400h. The part number 830-76129R identifies this exact rotor for precise fitment.
