• Weight approximately 23 lbs (10.45 kgs) for balanced performance

Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are designed with a vented construction featuring pillar-style vanes that promote efficient airflow and heat dissipation. The slotted surface helps to remove brake dust, gases, and water from the rotor surface, maintaining consistent braking performance. The coated hat finish protects against rust and corrosion, which is essential for maintaining rotor integrity over time. With a floating disc mounting system, these rotors accommodate thermal expansion and reduce the risk of warping under high-stress braking scenarios.

Precision dimensions such as a 326 mm outside diameter, 30 mm nominal thickness, and a 100 mm bolt circle diameter with 5 lug holes ensure proper fitment on compatible Subaru and Toyota models. The center hole diameter measures 58 mm (2.283 inches), and the rotor’s overall height is 52.9 mm (2.083 inches), matching OEM specifications for a direct replacement.
