Description
Upgrade the rear braking performance of your 2018–2021 Subaru WRX STI with FactionFab V2 Slotted Rear Brake Rotors. Designed for drivers who demand reliable braking performance, improved heat management, and long-term durability, these performance-oriented rotors combine high-carbon iron construction with precision machining and corrosion-resistant protection.
FactionFab V2 rotors are manufactured from premium G11H18 high-carbon iron alloy, engineered to effectively manage heat generated during repeated braking. The high-carbon material helps improve thermal stability, reduce vibration, and maintain consistent braking performance during daily driving, spirited street use, and demanding performance applications.
The rotor face features FactionFab's distinctive F-design slots, which help evacuate brake dust, gases, and debris from the brake pad contact surface. This design promotes more consistent pad-to-rotor contact and helps maintain predictable braking performance during repeated braking events.
For precise fit and consistent braking characteristics, each rotor is double-disc ground to achieve accurate thickness and a high-quality surface finish. The rotors are also mill balanced to help minimize vibration and provide smooth operation at various speeds.
A full Geomet zinc coating is applied to both the interior and exterior surfaces of each rotor. This protective finish provides enhanced resistance to corrosion caused by moisture, road salt, and other environmental contaminants while maintaining a clean appearance.
These V2 rear rotors feature a dual-drilled 5x100 and 5x114 bolt pattern, depending on the applicable configuration. Integrated M8 threaded removal holes make rotor removal easier during brake service, while the outer edge is clearly stamped with the rotor's part number and minimum allowable thickness for convenient identification and maintenance reference.
