Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.44105R) is designed specifically for Toyota Supra vehicles, providing a vented rotor with a 324 mm outside diameter and a 5-lug mounting pattern. The rotor’s cross-drilled and slotted surface improves brake pad bite and helps evacuate gases, dust, and water, which can accumulate during aggressive driving or wet conditions. The vented design with straight vanes enhances airflow through the rotor, reducing the risk of brake fade caused by excessive heat. The coated hat finish offers corrosion resistance, helping maintain rotor integrity over time.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors product line focuses on performance-oriented rotors that balance durability and heat management. This line features rotors with precision-machined slots and drilled holes to optimize braking efficiency and pad cleaning.
