The Subaru WRX STI Brake Rotor (2) - Front - StopTech - Slotted AeroRotor for the `13-`15 models serves as a high-performance replacement for your vehicle's original factory rotors. Designed to maintain the use of the factory brake calipers, these rotors offer a seamless transition while enhancing your vehicle's braking system.

StopTech's AeroRotor Replacement Kits (ARK) provide improved cooling, braking, and handling over stock rotors. These directional, floating AeroRotors are engineered to allow independent expansion without "coning," owing to elongated drive pin holes. The AeroRotor friction rings alongside billet aluminum AeroHats and their directional stand-offs are pre-assembled to optimize cooling airflow. Patented vane design enhances airflow, significantly improving cooling capacity and reducing fade during intensive track use. With the rotor and hat designed as two separate components, weight is minimized by up to 8 pounds, contributing to enhanced acceleration and deceleration.

Features

• Reduced unsprung and rotational mass.
• Improved thermal capabilities.
• Optimized heat dissipation.
• Compatible with OE calipers.
• Optional anti-corrosion zinc finish.

Made entirely in the USA, these two-piece AeroRotors are available either slotted or cross-drilled. These choices enable better dissipation of heat, friction material, and debris, ensuring fresh pad material contacts the rotor with each brake application.
