DFC 18-25 Subaru WRX STI Rear Drilled Hi-Carbon Alloy Geomet Coated Rotor

When you're looking to replace the rear brake rotors on your 2018-2021 Subaru WRX STI, especially if you push your car a bit, you want something that can handle the heat and stop reliably. These DFC rotors are built with G3000/G11H18 iron castings, which are well-built for strength and stability, giving you a solid foundation for your braking system.

What's neat about these is they keep the original equipment vane configuration, meaning they're set up to dissipate heat effectively, which is crucial for preventing brake fade during spirited driving or repeated stops. They're also precision mill-balanced to ensure you get smooth stopping power without any annoying vibrations, no matter how fast you're going. The fine-turned finish helps your new brake pads bed in properly from the start, and the Geomet coating offers good protection against rust and corrosion, keeping them looking good and working well for longer.

With a maximum disc thickness variation of just 0.010 MM and lateral runout of 0.050 MM, these rotors are made to very tight tolerances, which contributes to a better initial break-in and consistent performance. They're a solid option for getting your STI's braking system back in top shape.
