The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (Part Number 127.44047R) are engineered for enhanced braking performance on select Geo and Toyota vehicles. Designed specifically for models like the Toyota Corolla, MR2, and Geo Prizm, these rotors offer reliable stopping power with improved heat dissipation and reduced brake fade.

• Cross-drilled and slotted surface for efficient heat and gas dissipation
• Vented rotor design to maintain optimal operating temperatures
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for improved rotor alignment and performance
• Compatible with 4-lug wheel configurations and 100mm bolt circle diameter

Detailed Product Features and Specifications

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors feature a 10.15-inch (257.8 mm) outside diameter and a nominal thickness of 0.866 inches (22.0 mm), with a discard thickness of 0.827 inches (21.0 mm). The rotors have an overall height of 1.882 inches (47.8 mm) and a center hole diameter of 2.126 inches (54.0 mm). The vented rotor design incorporates straight vanes to optimize airflow and cooling during braking. The rotor surface is cross-drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape, improving pad bite and wet-weather performance. The hat area is coated to protect against rust and corrosion, enhancing durability over time.
