FactionFab Rear Brake Rotors Dual Drilled 5x100 / 5x114.3 Pair Subaru STI 2018-2021

Part #: FFA1.10147.1 - G. These rear brake rotors are a perfect choice for street driving and those occasional fast drives. They boost your overall braking response, enhance brake cooling, offer great thermal stability, keep brake pads clean, and improve braking performance in all situations. Details: Rear - mounted rotors with a 5x114.3 and 5x100 dual - drilled bolt pattern. The high - carbon cast iron disc has shallow, sharp - edged grooves, ensuring consistent pad contact and maximum friction over repeated use. High - carbon content makes them wear - resistant, thermally stable, and crack - resistant. They have a bi - directional design, so no need to worry about side - specific installation. Symmetric vane castings increase heat dissipation and thermal stability. The double - disc ground, non - directional finish gives a smooth look. They are mill - balanced to reduce vibration and precisely machined with a run - out spec of no more than.002' and Disc Thickness Variation (DTV) of.0005'. The fully machined non - friction surfaces ensure a perfect fit. They come as a pair. Black E - Coating: Electronically applied for corrosion resistance, passed a 400 - hour salt spray test, and fully coated inside and out. Note: 2008 - 2014 WRX models need factory OEM 2018+ STI Brembo Brakes for installation.

Using these FactionFab rear brake rotors is straightforward. Just install them following the standard brake rotor installation process for your Subaru STI 2018 - 2021. If you have a 2008 - 2014 WRX model, remember to use the factory OEM 2018+ STI Brembo Brakes. For maintenance, regularly check the brake pads and the rotors themselves. Look for any signs of excessive wear or damage. Since the rotors have a black e - coating for corrosion resistance, there's no need for additional coating. But keep them clean to ensure the best performance. If you notice any strange noises or vibrations while braking, it might be time to have them inspected. With proper use and care, these rotors will serve you well for a long time.
