Detailed Product Description

This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for maintaining consistent stopping power. The drilled and slotted surface helps evacuate gases, dust, and water, contributing to better brake pad contact and reduced brake fade. The rotor’s plain disc finish combined with a zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 18 mm and a discard thickness of 16 mm, this rotor meets precise specifications for safe replacement intervals.

The 5-bolt hole pattern with a 150 mm bolt circle diameter and 16.3 mm stud/lug hole diameter ensures compatibility with the specified Lexus and Toyota models. The directional surface design is intended to optimize braking efficiency and pad wear.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots for enhanced brake cooling and debris removal.
