Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors 126.42011SL are designed to provide consistent braking performance with a focus on heat management and pad cleaning. The slotted surface helps to evacuate gases and debris from the brake pad interface, reducing brake fade and maintaining effective stopping power during aggressive driving or track use. The solid rotor design offers structural integrity and is suitable for applications where vented rotors are not required. The coated hat finish enhances corrosion resistance, extending rotor life in various environmental conditions.

These rotors feature precise dimensions including a 10.669 inch (271 mm) outside diameter and a nominal thickness of 0.492 inches (12.5 mm), with a discard thickness of 0.413 inches (10.5 mm) to ensure safe replacement intervals. The mounting configuration includes four bolt holes with a 4.055 inch (103 mm) bolt circle diameter, compatible with vehicles requiring this specific fitment. The rotor mounts behind the hub, which is typical for many passenger cars and light trucks.

StopTech Sport Slotted Disc Brake Rotors Product Line

The StopTech Sport Slotted Disc Brake Rotors line is engineered for drivers seeking enhanced braking performance without the complexity of vented rotors. This product line focuses on solid rotors with slotted surfaces to improve pad bite and heat dissipation, making them suitable for spirited street driving and occasional track use. The 126.42011SL rotor exemplifies this approach by combining durability, corrosion resistance, and effective braking characteristics in a straightforward design.
