Product Details

Wilwood is well-known for making high-performance braking components. This SRP Drilled Performance Rotor is a great example of their focus on improving stopping power. It features a directional cross-drill and face slot pattern designed to work with your brake pads, helping to improve your car's brake response and overall pad performance, whether you're doing light braking or heavy stopping.

The holes and slots on this rotor do more than just look good; they actively help your brakes work better. They help clear away gases and heat that build up between the pad and rotor during braking, which can prevent pad glazing and keep your pedal feeling consistent. This cleaning action also helps stop uneven pad material from building up on the rotor surface, leading to smoother engagement and a more predictable pedal feel in all sorts of driving conditions. Plus, the material removed to create these features also helps reduce the rotor's rotating and unsprung weight, which can have a positive effect on your vehicle's handling.

This rotor measures 12.44 inches in diameter and is 1.19 inches thick, with a 12x7 inch bolt pattern and 48 vanes for good airflow. It comes in a black finish.
