• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting design for better thermal expansion management
• Compatible with 5-lug wheel configurations and 5.5-inch bolt circle diameter
• Nominal thickness of 1.102 inches (28.000 mm) with discard thickness at 1.039 inches (26.400 mm)
• Outside diameter of 13.228 inches (336.000 mm) and overall height of 2.650 inches (67.300 mm)

Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors (126.67053SR) feature a vented design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The slotted surface helps to evacuate brake dust, gases, and water, maintaining consistent pad contact and improving braking response. The coated hat finish protects against rust and corrosion, which is essential for maintaining rotor integrity over time. These rotors are designed with a floating disc mounting system that accommodates thermal expansion, reducing the risk of warping under heavy use.

With a center hole diameter of 3.091 inches (78.500 mm) and a stud/lug hole diameter of 0.669 inches (17.000 mm), these rotors fit vehicles equipped with a 5-lug wheel pattern and a 5.5-inch bolt circle diameter (139.700 mm). Weighing approximately 25.5 lbs (11.59 kgs), they balance durability and performance for daily driving and moderate performance applications.
