The Wilwood 160-3306 is a solid, drilled steel front rotor with a 6 x 6.25-inch bolt circle. The manufacturer lists a width of 0.35 inch, a diameter of 10.75 inches, a black oxide surface finish, and a weight of 4.70 pounds. Its mount is non-direct, so it is designed to sit on a separate hat rather than bolt straight to the hub.
Wilwood positions this rotor for medium-duty drag racing and states that it is not intended for street use, so it is a purpose-built choice for sanctioned drag strip running rather than a budget daily-driver upgrade. Choose it over a generic street rotor when you want documented dimensions and a race-specific intended use for a 10.75 drag drilled steel front setup. Note that the manufacturer lists drag racing as the driving environment, with medium duty as the application rating.
Before ordering, confirm that your hub is a 6 on 6.25 pattern and that your hat and caliper package accepts a 0.35-inch-thick rotor. The manufacturer's listing indicates the rotor is not balanced and not burnished, so plan to check balance and follow a proper pad bedding procedure during installation.
