Product Description

The Wilwood 160-14040-BK SRP Drilled Performance Rear Rotor & Hat is an upgrade rotor assembly designed specifically for rear passenger side applications on C5 and C6 Corvette models. Its drilled and slotted surface enhances heat dissipation during spirited driving and helps maintain consistent pad contact by reducing glaze and debris buildup. The black electro-coat provides corrosion resistance and an aggressive appearance, although this finish typically wears off the braking surface during bedding.

This rotor and hat assembly is precision machined for low run-out and flatness, ensuring smooth braking performance with OEM or performance pads. It fits 1997-2004 Corvette C5 and 2005-2013 Corvette C6 vehicles on the rear passenger side (right-hand). Installation integrates with existing hubs that accept the 5x4.75 in bolt pattern, making it a straightforward upgrade for enthusiasts looking for improved rotor cooling and brake feel without a full big-brake kit.
