Wilwood Rotor 1175-125DN638-000TJCXXXXR

This is a Wilwood 2-piece brake rotor, part number 160-16027-B. It's built with a 11.75-inch diameter and a 1.25-inch thickness, designed for applications where improved braking performance is a priority. The rotor features a GT-style hat, which is a common feature on performance brake setups, and it's constructed with 48 curved vanes. These vanes help to move air through the rotor, aiding in heat dissipation during hard braking.

The 2-piece design separates the rotor ring from the hat. This construction method allows for better thermal management, as the hat can be made from a lighter material like aluminum, and it also makes replacement of just the rotor ring easier if it wears out. The specific vane count and curvature are engineered to help manage the heat generated by friction, which is crucial for maintaining consistent stopping power, especially during repeated braking events.
