Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.47036L) feature a vented rotor design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact and improving stopping power. The rotor’s coated hat finish offers protection against rust and corrosion, extending the rotor’s service life. With an overall height of 56.7 mm and a center hole diameter of 58.0 mm, these rotors are designed for precise fitment on Subaru models such as the WRX and Outback. The floating disc mounting system allows for slight rotor movement, which can help reduce brake judder and improve pedal feel.
