Wilwood's Rotor Mounting Hats have been precision machined from high strength, lightweight aluminum alloy. We offer a wide range of offsets and wheel stud patterns for Drag Race, Street Rod, Pro Series, Stock Car, Modified, Off Road, Open Wheel and Rally. All are designed to provide maximum weight savings and durability. Many are available unmachined to accommodate custom stud bolt circle applications.

We also offer a spun steel hat as required for use in certain late model classes.

Most Wilwood hats are black plated to accelerate heat dissipation and prevent corrosion.
