Detailed Product Description

This DFC Brake Rotor from Dynamite Friction features a drilled and slotted design that improves brake pad bite and helps evacuate gases, dust, and water from the rotor surface. The vented construction promotes better airflow to reduce heat buildup during braking, which is critical for maintaining consistent stopping power and minimizing brake fade. The rotor’s zinc black hat finish and rust-resistant coating provide enhanced corrosion protection, extending the rotor’s service life in various driving conditions.

With a nominal thickness of 22 mm and a discard thickness of 19 mm, this rotor meets OEM specifications for thickness and durability. The 255 mm outside diameter and 46.3 mm height ensure proper fitment and compatibility with the braking system of Toyota Prius C, Yaris, and Scion iQ models. The 4-bolt mounting pattern with a 100 mm bolt circle diameter matches factory configurations for secure installation.
