• Nominal thickness of 0.945 inches (24.000 mm) with discard thickness at 0.866 inches (22.000 mm)
• Outside diameter of 10.898 inches (276.800 mm) and overall height of 2.232 inches (56.700 mm)

Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are precision-engineered vented rotors featuring a cross-drilled and slotted surface pattern. This design enhances brake pad bite and helps evacuate gases, dust, and water from the rotor surface, which is especially beneficial during spirited driving or in wet conditions. The vented construction with straight vanes promotes consistent airflow, reducing heat buildup and minimizing the risk of brake fade. The coated hat finish provides corrosion resistance, maintaining rotor integrity over time. These rotors use a floating disc mounting system, which allows slight movement between the rotor and hub to reduce stress and potential warping during thermal expansion.

With a center hole diameter of 2.283 inches (58.000 mm) and stud/lug hole diameter of 0.504 inches (12.800 mm), these rotors are designed for vehicles with a 5-lug wheel pattern and a 100 mm bolt circle diameter. Weighing approximately 14.5 lbs (6.59 kgs), they balance durability with manageable unsprung weight.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Product Line
