Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are precision-engineered vented rotors featuring a cross-drilled and slotted surface. This design enhances braking performance by allowing gases and heat generated during braking to escape more efficiently, reducing the risk of brake fade. The vented construction with pillar-style vanes promotes airflow through the rotor, maintaining optimal operating temperatures during aggressive driving. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. These rotors have a floating disc mounting system that allows slight movement between the rotor and hub, which helps prevent warping and ensures consistent contact with brake pads.

With a nominal thickness of 1.181 inches (30.000 mm) and a discard thickness of 1.118 inches (28.400 mm), these rotors meet strict specifications for durability and performance. The 12.756 inch (324.000 mm) outside diameter and 1.933 inch (49.100 mm) overall height are designed to fit the brake assemblies of Nissan 350Z and Infiniti G35 models. The rotor includes five lug holes with a 4.5 inch (114.3 mm) bolt circle diameter and a center hole diameter of 2.677 inches (68.000 mm), ensuring proper fitment and secure mounting.
