Stoptech 18-20 Subaru WRX/STI Rear Right Slotted Sport Brake Rotor

When you're pushing your 2018-2021 Subaru WRX STI hard, especially on the track or during spirited drives, you want your brakes to respond with confidence. This Stoptech Slotted Sport Rotor is designed to replace your stock rear right rotor, offering a noticeable improvement in braking feel and performance. It's built with advanced metallurgy that helps quiet down pad noise, making it a great match for higher-friction brake pads, including European-style compounds. The unique slotting pattern isn't just for looks; it actively helps to clear out heat, brake dust, and gases from the rotor surface. This means your pads stay cleaner and maintain better contact, leading to a more consistent and powerful bite, whether you're braking in dry conditions or in the rain.

Beyond the slotting, this rotor is constructed for durability. It features a black E-coating on the non-friction surfaces to protect against corrosion, keeping your components looking good and functioning properly for longer. The high carbon metallurgy contributes to quieter operation, better resistance to cracking from heat cycles, and overall increased performance. Stoptech double disk grinds the friction surface for a consistent contact area, and the directional vane design (on applicable models) further aids in heat management. This rotor is a direct OE replacement, meaning it fits right onto your factory brake system without modification.
