StopTech Slotted Sport Rear Brake Rotor for 2018-2021 Subaru WRX STI

Description

Upgrade your Subaru WRX STI with the StopTech Part Number 126.47039SR slotted sport rear brake rotor, designed to deliver superior braking performance and enhanced durability. Crafted from high-carbon metallurgy, this rotor features a black e-coating that provides excellent corrosion resistance, ensuring long-lasting performance in various driving conditions. Its one-piece construction makes it a reliable replacement for factory brake discs, seamlessly fitting your stock calipers and brake system.
The rotor’s unique slotting design is engineered to improve heat dissipation and brake dust evacuation, reducing glazing and maintaining optimal contact between the pad and rotor. This results in increased initial bite, better wet weather response, and more consistent braking performance. The double disk ground surface ensures a smooth, uniform friction surface, while the directional curve vane design on selected applications enhances airflow for cooling.
Cryogenic treatment applied to the rotor reduces residual stress, further improving crack resistance and thermal stability under demanding driving conditions. These features collectively contribute to quieter operation, improved crack resistance, and increased resistance to thermal stress fractures. The slotted design not only boosts performance but also adds a sporty aesthetic to your wheels, making your vehicle stand out while providing confident braking in both dry and wet conditions. This rotor is a direct OE replacement, offering an easy upgrade for owners seeking high-performance braking components for their Subaru WRX STI.
